Here comes the long-awaited moment when a young family or a married couple begins to think about the appearance of a little man who will be a continuation of their kind. In the early stages of this period, difficulties and pitfalls begin to appear, because every fourth family has difficulties in conceiving a child. Lack of ovulation is a limiting factor.
Any woman who is planning a pregnancy should understand on what day after her period ovulation occurs. Ovulation is a process accompanied by the release of a ripened egg from a bursting follicle. Let's take a little look at this process. The menstrual cycle of any woman is divided into two important points - the follicular and luteal phases. At the beginning of the cycle exactly to the middle, the follicle ripens, it breaks and moves ready to merge with the sperm cell of the egg into the abdominal cavity. All this happens under the action of the sex hormones estrogen and progesterone, produced by the hypothalamus and the endocrine system as a whole. This is ovulation. If the merger has not occurred, then the mature egg together with the inner layer of the walls of the uterus come out in the form of bleeding. Maturation is determined by the middle of the menstrual period. Ideally, with a 28-day cycle, the maturation of the egg will occur approximately 13-15 days after the onset of menstruation. There are cases when ovulation during the menstrual cycle occurs twice. This is associated with any infectious diseases, improper endocrine system, stress.
Every girl who has reached sexual maturity should be able to count the menstrual cycle. On average, it lasts 21-35 days. But there are cases when the cycle lasted less than 18 days and more than 45 days. Monthly periods can get off depending on different situations: childbirth, abortion, lactation. And during pregnancy, they generally cease to go.
Many couples raise the question "on what day after their monthly ovulation occurs" in search of an answer only to insure against the possibility of becoming pregnant using the calendar method. But this is not necessary, because, as mentioned above, the maturation of the egg in critical situations can be repeated in one menstrual cycle. Yes, and ovulation due to health conditions can shift by 1-2 days within the cycle. Even if you manage to get between the "dangerous days", this type of contraception will not protect against infection.
Some women have an increased attraction, or so-called libido, during the maturation of the germ cell. Abundant secretions are also associated with a ripened follicle rupture. A sharp decrease and then a rise in temperature, measured rectally, may be an echo of incoming ovulation. But all these methods are imperfect and do not give an absolute guarantee. The most accurate diagnostics can be called studies conducted by ultrasonic radiation.
On which day after the monthly ovulation occurs
Let's still figure out on what day after the monthly ovulation occurs. Take as a basis the standard 28-day menstrual cycle. When dividing in half, we get the 14th day, from which it is worth repelling. When ovulation occurs after menstruation, a mature egg leaves the follicle in search of a spermatozoon. If we take into account that the spermatozoid life is not more than three days, in particular cases it reaches a week, and the egg is ready to wait for the meeting for only 12-24 hours, then the number of “dangerous” days is equal to a week as much as possible.
Answering the question on which day ovulation occurs, it is worth highlighting the main points:
• the menstrual cycle is calculated from the first day of the month last month to the first day of the next menstruation,
• ovulation falls exactly in the middle of the cycle or it can shift for 1-2 days,
• lack of ovulation may be due to a number of reasons, which must be diagnosed under the supervision of qualified professionals,
• in the absence of menstruation should immediately contact the antenatal clinic.
The time of arrival of ovulation
No gynecologist will be able to answer with accuracy, after how many days after menstruation ovulation occurs. This indicator is individual for each woman. The time of maturation of the egg depends on how long the whole menstrual cycle lasts and the duration of each stage.
If the cycle includes 28 days, ovulation occurs exactly in the middle. The egg matures on day 14. This exact time is peculiar to units only. In some women, the menstrual cycle is unstable. In this case, ovulation may be every new month at different times.
It should be noted that in women who do not have problems with the health of the reproductive system, 1-2 times a year, the menstrual cycle is possible without the maturation of the egg. This phenomenon is called anovulation. The onset of conception this month is impossible. This is not a pathology. The ovaries will resume normal functioning in the next cycle.
Ovum matures approximately mid-month cycle
How long does ovulation last
The duration of the menstrual cycle can vary from 21 to 32 days. The whole period is usually divided into 4 stages. The ovulation stage is the middle of the cycle. This is a short length of time. Its maximum duration is 2 days, which is due to the short life of the egg. This is also an individual feature.
In some women, the egg cell is suitable for fertilization within 48 hours, but usually this time is much less.
On the days of the ovulation phase, the sheath of the dominant follicle is broken in one of the ovaries. From it comes a ripe egg. She begins to slowly move through the fallopian tubes towards the uterine cavity. If during these 2 days the woman had unprotected sex, then the probability of conception is very high.
Mature egg moves through fallopian tubes
What caused the onset of ovulation
The length of the cycle is influenced by the duration of the first stages - menstrual and follicular. During this time, the uterine cavity gets rid of unnecessary endometrium. Together with bleeding during menstruation, the unfertilized egg in the past cycle is also removed from the body. Menstruation can last from 3 to 5 days.
After this comes the follicular phase. The female body these days is actively preparing for the intended pregnancy. In the ovaries begin to develop follicles, one of them will have a maximum size. From him at a certain time and the egg will be released.
The longer the woman's menstrual cycle, the more time is given to the stage of maturation of the follicles. Just say what day the egg will be released is unrealistic. These processes are controlled at the hormonal level. The pituitary and hypothalamus, the endocrine glands, which are elements of the brain, are responsible for the production of estrogen and progesterone by the ovaries. Ovulation occurs as soon as the concentration of follicle-stimulating and luteinizing hormones of the pituitary gland becomes maximum. The ovaries respond to this by increased secretion of estrogen.
The follicular phase actively prepares the woman's body for fertilization
How to calculate the onset of ovulation
Immediately after the ovulation phase, which may be 1 or 2 days, the luteal stage begins. Its duration is 14 days. It is constant in most women with a stable cycle. This allows you to calculate how many days after menstruation ovulation occurs. Many women use this universal method:
- For counting it is required to know from what date the menstruation began last month. This date should be noted in the calendar.
- Further, it should be noted on what day the first selections appeared in the new month. The previous day will complete the cycle.
- After that, you need to calculate the total number of days. If they are 28, then ovulation occurs on the 14th day.
- In the event that the length is more or less than the standard value, then this number should be subtracted from 14. Thus, with a cycle of 30 days, ovulation occurs on the 16th day.
This method allows you to calculate the days of arrival of ovulation with an error of 1-2 days. The probability of conception becomes maximum. To clarify what day the ripe egg will be released, you should pay attention to indirect signs.
The fact that ovulation occurs is indicated by an increase in basal temperature. The method is reliable only with regular use. To determine which day is marked by a jump, measurements are required every morning.
On the day of the rupture of the follicle, slight pain in the abdomen may occur. High probability of conception is also indicated by transparent mucous secretions in the middle of the cycle. This indicates that ovulation occurs.
These methods do not allow you to accurately determine the day when egg maturation occurs. It may be sooner or later. To increase the likelihood of conception, attempts to become pregnant should begin 2 days before the intended ovulation. This is due to the long-term viability of sperm.
Optimally determine the days when ovulation occurs, using a special test. Ultrasound diagnostics is even more informative. The device can show the moment of rupture of the follicle.
When using the calendar method of protection, it is assumed that ovulation before menstruation is impossible. However, this does not mean that the probability of conception is absent. There is no single day of ovulation. It can be at different intervals of the cycle. Phases are often lost due to stress, exercise, or climate change.
What is ovulation?
it ovarian exit process ripe egg cell. These cells are laid in the girl's body even during embryonic development.
With the onset of puberty about once a month in the ovary under the action of hormones, one egg matures (sometimes several), which at the time of ovulation leaves it and enters the uterus.
Further options for the development of the event are two:
- With unprotected intercourse, fertility is likely. This happens if the egg cell itself is viable, and the sperm cells are quite mobile. In this case, after the merger of two cells, a zygote is formed.
- If fertilization does not occur, after a few days the dead egg together with the endometrium (the inner lining of the uterus) leaves the body.
Externally, it is not noticeable
Externally, it is not noticeable. But if a woman listens to her body, she will surely notice some changes. In some women, the signs of ovulation are more pronounced, in others - almost imperceptible.
The most reliable are:
- Increase in quantityvaginal secretion. It occurs under the influence of estrogen. If at the beginning of the cycle the excretions were liquid and watery, closer to the middle of the cycle they thicken, acquire the consistency of egg white.
- Increase in basal temperature. But this symptom is rather conditional: the temperature can rise to subfebrile values at the beginning of a cold, and against the background of a chronic inflammatory process.
- Increased sexual desire due to hormonal adjustment, as well as the instinct of reproduction in the most appropriate period.
- Swelling and increased breast sensitivity. Sometimes women describe these feelings as unpleasant.
- Bloatingassociated with the activity of hormones and irritation of the peritoneum during the rupture of the follicle. These sensations are enhanced in the presence of chronic diseases of the female organs.
- Hypersensitivity to tastes and smells.
- Pain in the abdomen - from mild aching pain to acute, spastic.
The duration of ovulation and menstrual cycle for women is individual. Normally she is from 28 to 35 days.
Deviation in any direction for more than 2 days indicates the presence of pathology: inflammation, hormonal and other problems. Even if the monthly with painless, and no other symptoms, additional examination will not hurt.
The monthly cycle of a woman is divided into 4 phases, each of which is associated with the production of a specific sex hormone:
- MenstrualThe bleeding period lasts from 3 to 6 days.
- Follicular - the period when the egg matures. It lasts about 2 weeks. In this is produced FGS - follicle stimulating hormone. The woman is at the peak of physical and emotional endurance. The discharge during this period is fluid, the cervix is insensitive to sperm.
- Ovulationwhich lasts about 3 days. The production of FSH decreases, and the level of luteinizing hormone reaches its peak values (this is the basis for the ovulation test). After exiting the follicle (approximately 24 hours after the LH peak), the egg cell is capable of fertilization for several hours.
- Luteal, its duration is up to 16 days. During this period, the production of progesterone increases, the task of which is to prepare the endometrium for embryo attachment.
If conception occurs, the fertilized egg is fixed in the uterus, in the woman's body begins to produce choriogonic gonadotropin (pregnancy hormone).
What day after menstruation comes?
After the last day of the month, about 10-14 days pass. But the exact day is quite difficult to calculate This is influenced by a number of factors.: the presence of chronic diseases, the stability of hormonal levels, stress, weight, level of physical activity.
Disease, potent medication, severe stress able to move ovulation for an indefinite period or not to allow it at all in the current cycle.
To determine the approximation of ovulation, you can:
- Using test strips sensitive to luteinizing hormone.
- Using ultrasound of the ovaries.
How to calculate the exact date?
Temperature. From the first day of menstruation woman must measure at the same time in the morning basal temperature. For this, a thermometer is inserted for 5-7 minutes into the rectum. At the beginning of the cycle, it will be stable, and on the eve of ovulation it will increase by a few tenths.
Rapid tests. From about 10-12 days of the cycle at the same time (better by noon) with the help of test strips you need to determine the level of luteinizing hormone. If the strip is pale, the level of LH has not yet reached a peak. On the eve of the release of the egg from the follicle strip will be a rich color.
According to the consistency of vaginal discharge. On the eve of ovulation, they thicken. But if a woman drinks a lot of fluids, it will be difficult to notice the difference.
How to determine the last menstruation?
According to the last monthly calculations, calculate the most probable day for fertilization. can only be the caseif a woman has a stable cycle.
If the monthly irregular - ovulation occurs every time at different times, and it is useless to rely only on the date of the beginning of the month.
If the cycle is stable, the date can be calculated using the following formula: it takes 14 days to take a cycle.
There is another way: add the duration of the bleeding itself to add 10-14 days to the date of the beginning of the last menstrual period. This method is less effective, but will allow to determine approximate terms. For a more accurate determination of ovulation, you can use a special test or a temperature method.
Can it start right after your period?
This is possible in several cases:
- If there was a hormonal failure.
- When a woman has a short cycle, but the bleeding itself lasts more than 6 days.
- After a delay of menstruation, caused by stress or hormonal disruption.
Ovulation in this case is full, and the probability of conception is high.
Why is absent - anovulation
Anovulation may be:
- Physiological - during pregnancy and in the first months after childbirth, during menopause.
- Temporalassociated with severe body overload. This can be a strong emotional experience, excessive physical exertion, abrupt recruitment or weight loss, taking medications. As soon as the woman's condition stabilizes, ovulation returns.
- Chronic. It is caused by the presence of diseases of the sexual sphere. This is usually a polycystic ovary syndrome, excessive production of male sex hormones, endocrine diseases, including diabetes.
The most effective tactic to determine ovulation - for several cycles observe the body and apply multiple date counting methods.
If within 3 cycles the egg cell in a row will leave their follicles on the same day of the cycle - the accuracy of subsequent predictions will be as close as possible to 100%.
What cycle is normal?
Identify on what day ovulation occurs after menstruation, permissible by mathematical methods, physical or with the help of a doctor. But first it is necessary to understand the duration of its cycle and the features of this process. To calculate the female cycle, it is necessary to keep a calendar in which to mark the first days of the month. Having calculated the number of days between marks, you can determine the duration of the cycle. It is considered a norm for 28 days, but usually it varies in the range of 27-29. У некоторых дам периодичность может отличаться от нормы и быть в пределах 25-35 дней.
Календарь менструаций поможет высчитать женский цикл
Если вести календарь овуляции некоторое время, можно определить, насколько женский ритм жизни статичен. If no oscillation is detected, the calculated number is taken as the initial number for further calculations.
Disruptions in ovulation
However, there are situations involving failures:
- Moving to a region with a different climate
- Rest in an atypical climate,
- Stressful situations.
If the failure in the calendar was accompanied by one of the explainable reasons, you should not pay attention to it. If no clear explanation is found, this indicates irregularity, which is accompanied by a more difficult determination of the optimal day for conception.
Algorithm for calculating the day of ovulation
Understanding the process of ovulation, you should know that it falls almost in the middle of the female cycle - between the follicular and lutein process. The first is characterized by maturation of the germ cell in the ovary and can last an average of 11 days. The second one is static and always lasts 14 days, and ends with the blood discharge of the next menstrual period. Between them, and have a short period of time (1-1.5 days), which is called ovulation.
The increase in the chance of fertilization at this point is explained by the fact that the cell left the ovary and entered the fallopian tubes. With a good effect, here the sperm will reach it, and already fertilized, it will be fixed on the wall of the uterus.
Knowing these simple facts, it is very easy to reveal on which day ovulation occurs after menstruation. It is enough to subtract 14 from the duration of the cycle (14) (luteal phase). The resulting number indicates how much you need to count from the onset of menstruation.
Following this rule, we get the following values:
- On the 12th day, with cycle 26.
- 13th - 27,
- 14th - 28,
- 15th - 29,
To determine the date of occurrence using the ovulation calendar, you must enter the parameters:
- the last day of the month
- cycle value.
It is possible to enter these data only for the last two months. That is, in order to understand on what day after menstruation ovulation occurs, it is not necessary to observe the body for a long time. But this calculator is not very helpful if the girl’s life rhythm is unstable. In this situation, the calculation methods are not accurate. It is better to try others.
Ovulation tests - when to use
To determine which day after the start of menstruation ovulation is more likely, use special tests to determine it. They are quite accessible and work on a similar principle as test strips for pregnancy. The difference is the reagent with which they are impregnated.
When the egg comes out, the follicle in which it matures is torn. Luteinizing hormone (LH) is released into the body. It is his great concentration, the so-called “surge”, that indicates the imminent entry of the cell into the fallopian tube.
Ripe egg cell breaks follicle
The test reveals the level of LH in the urine. The bright band on it indicates a high content of LH. Then after 10-12 hours ovulation will occur.
In order not to miss the moment, measurements should be carried out 17 days before the end of the cycle:
- 14 - on what day after ovulation come monthly (luteal phase),
- 3 - the maximum possible period of ovulation.
Subtracting from cycle time 17, we get the day the sample starts (for example, the 11th at 28 days). They should be held every day or two times (if there is a chance to miss this short period) at the same time, following the instructions. You also need to limit the amount of fluid consumed in a few hours so that it does not lower the level of LH concentration, and do not go to the toilet for 2-3 hours prior to sampling.
The normal level of LH is different for each woman. Some women may find a bright streak every day. This suggests a constant large content of LH. For this situation, this method will be ineffective.
Determination of ovulation by well-being
The best way to find out on which day ovulation begins after menstruation is to watch your feelings. In particular, the egg, leaving the ovary, breaks through its wall. It forms a small wound, which, of course, brings discomfort. It is expressed in pain in the area of the ovary and lower abdomen. In this case, the ovaries work alternately, with rare exceptions. Therefore, pain can be observed from either side. Sometimes the belly swells a little. This is also a normal reaction to the passage of the egg through the pipes. Sometimes it is accompanied by gas.
In addition, the obvious signs of fast ovulation consider:
- Painful, swollen breasts - the body prepares to reproduce offspring.
- Atypical discharge - thick, bulky, abundant. Different in color - transparent.
- Increased libido. A woman is subconsciously ready for fertilization. Observed a couple of days before ovulation.
Of course, there are changes in the level of hormones in the blood and urine, and in the cervix, but this list is enough to determine the onset of the long-awaited moment. Although not everyone has it explicitly and can be missed.
What gives a graph of basal temperature
If a woman has an irregular cycle and the methods listed above are not suitable for her, there is the most accurate way to determine ovulation and on what day after her period. It is long and laborious, but sometimes the expectant mother has no other choice.
It is called the basal temperature chart. It is prepared on the basis of daily temperature measurements rectally. It is better to do this in advance (from 3 months), following simple rules:
- The beginning of the schedule - the first day of menstruation.
- Measurement is the first thing that is done in the morning, even without leaving the bed.
- Unnecessary movement may affect accuracy. Even prepare and "shake off" the thermometer is in the evening.
- During the illness, it is better to postpone the measurement so as not to distort the picture.
- When drinking alcohol, you should put a note-explanation on the chart.
The schedule itself is quite simple to perform. Two axes of coordinates: on the vertical part is the temperature, on the horizontal - days. Every day a point is put in the corresponding plane. After the end of the month, they are joined by a curved line.
A graph of basal temperature measurement will help determine the date of onset of ovulation after menstruation.
To decipher the curve, it is necessary to return to the ovulation process, which is characterized by the following values:
- The normal human temperature is about 37 ° C.
- The egg leaves the ovary, the hormone is released, which leads to a decrease of 0.4-0.6 ° C.
- The end of ovulation - an increase in temperature almost to the norm (but slightly lower).
- Luteal phase - normal temperature or lower by 0.1-0.2 ° C.
- Before the first day of menstruation - a decline of 0.3-0.4 ° C.
Thus, until the next menstruation, we will observe two drops, somewhat different from each other. The first, more pronounced, is our “auspicious moment.” If you observe constantly, the day of ovulation after menstruation a woman will know in advance.
Of course, do not forget about the most reliable method - ultrasound. The doctor will be able to observe the development of the follicle, name the auspicious day, and then follow the successful conception.
Ultrasound - one of the most accurate methods for determining the date of ovulation
Using the method that is most suitable for you from all of the above, you can determine with great precision the date of the onset of ovulation after menstruation.
The process of maturation of the egg
The formation of the egg ends approximately in the middle of the menstrual cycle. When the egg is fully ripe, the follicle breaks and the egg moves into the uterine tube. If fertilization occurs, a yellow body is formed. This phase of the cycle is called the luteal phase. With a lack of the hormone progesterone, the risk of miscarriage and miscarriage is very high. Therefore, a young mother should definitely monitor her state of health and regularly undergo scheduled examinations.
For example, consider the menstruation cycle, the duration of which is 28 days. With this cycle, ovulation occurs on day 14 and lasts an average of one day. The duration of ovulation is influenced by external factors and stimuli, as well as the individual characteristics of the woman’s body.
When the integrity of the follicle is broken, the egg leaves it and begins to pass through the fallopian tubes towards the uterus. If at this stage the sperm reaches the target and fertilizes the egg, a zygote is formed that will continue to the uterus. The ovum retains its ability to fertilize for about a day. Rare ovulation is considered a rarity, which lasts 48 hours.
Not the onset of pregnancy provokes a decrease in the level of progesterone, as well as the death of a particular layer of the uterus - endothermy, which leaves the body through blood discharge. The first day of the onset of menstruation bleeding is considered the first day of the new cycle.
What day does the egg mature after menstruation?
The egg's readiness for fertilization is determined in several ways. It is not necessary to use all methods simultaneously, it is enough to choose the most convenient for a woman. So, you can determine the day of ovulation using:
- calendar calculations,
- measurement of basal temperature
- use of special tests for ovulation,
- Ultrasound examination,
- analysis of their own feelings and well-being.
Each method has its own advantages and shortcomings in the accuracy of determining the ovulation period. It is especially difficult to calculate the maturation of the egg with an irregular menstruation cycle and with its failure. It should be borne in mind here that ovulation may be late, for example, after 19-20 days from the first day of the onset of bleeding. It is also possible to ovulate early, when the egg from the follicle occurs already 5 days after the onset of menstruation. Provided that a woman is healthy, similar disruptions in the body of a woman are allowed, but not more often than twice a year.
Methods for calculating ovulation
To determine when the maturation of the egg after menstruation occurs in several ways. If after applying any way to establish this period failed, do not despair. Perhaps the practical application of another technique will be more successful and the desired pregnancy will soon come.
- The definition of ovulation calendar method
This method is recommended to be applied on condition of regular monthly with a certain number of days in the cycle. If a woman’s cycle time is always different, the use of calendar counts is unlikely to be effective. In addition, the constant failure of menstruation are sufficient reason to visit the gynecologist.
During half a year it is necessary to fix the duration of cycles. From the obtained results the shortest and longest cycles are selected. The number 17 is subtracted from the value of the short cycle, that is, with a cycle of 22 days, we find that the first favorable day for conception is the 5th day of the cycle. If unprotected sexual contact takes place on this day, the spermatozoon will not lose its fertilization capacity by the time ovulation takes place (in this case it is 9-10 days of the cycle).
From the value of the longest cycle is subtracted 11. For example, 32-11 = 21. Where 21 days is the last day suitable for conception. Recall that often the viability of the egg is maintained for about 24 hours, so ovulation occurs no later than 20 days of the menstruation period.
- Measurement of basal temperature during ovulation
The reliability of this method is questioned by many experts. However, if within 4-5 months to accurately plot the BT, the woman will be able to calculate the date of ovulation after menstruation.
To understand that ovulation has occurred, it is possible by the following features:
- the establishment of the normal value of BT after menstruation at 36.5 ° C,
- a sharp drop in BT in the middle of the cycle,
- the rapid increase in BT to 37.2 ° C.
Increased temperature indicators indicate the onset of ovulation, which can last about two days.
- Test and ultrasound diagnostics
Specially designed tests for determining ovulation can be purchased at pharmacies. With a cycle duration of 28, the onset of ovulation is expected on day 14. It is recommended to make the first test on the 9th day of the cycle. A test is done daily for the next 5 days. One of the tests should show that the favorable moment for conception has come.
A visit to an ultrasound consultation is quite a costly method, but also the most accurate. Thanks to the ultrasound monitoring, the doctor closely monitors the processes in the ovaries and uterus. After analyzing the results, he will be able to accurately announce on what day ovulation will occur.
The maturation of the egg does not always occur on schedule. Due to the fact that the female body is more susceptible to stress and other adverse factors, it may take time to determine a successful period for conception. The main advice that future mothers should adhere to is to listen to their body and try to keep calm.
Features of the development of germ cells in women
The maturation of female germ cells is a very complex process and it occurs every month with a certain cyclical nature.
When a girl is born, she already has a certain number of such cells in her body. When puberty begins, the germ cells that are in the ovarian follicles mature and leave them into the abdominal cavity, ready for conception.
The menstrual cycle is the period from the beginning of the month to the beginning of the next critical days. For most women, it lasts 28 days. But given the individual characteristics, it may take from 25 to 35 days. During the menstrual cycle, in the absence of any gynecological abnormalities, several eggs mature. One or several of them are fertilized, and pregnancy begins or they all die.
Maturation of germ cells occurs under the action of female hormones. When pregnancy occurs, the hormonal background changes, and ovulation (maturation of the germ cells) does not occur.
Ovum maturation period
The menstrual cycle of most women lasts 28 days. Maturation of the germ cell occurs in the middle of the cycle. From here it is easy to calculate that, on average, this process falls on the 14th day of the cycle.
But all these calculations are purely theoretical, for reality may change under the influence of stress, lifestyle, nutrition, past infectious diseases. Maturation of the female germ cell can occur between the 13th and 15th day of the menstrual cycle. Happens and such that ovulation happens and 2 times, and there are cycles and even without its occurrence.
The brain controls the entire process when the egg matures after regular periods. The maturation of the germ cells consists of three phases:
- Follicle development (proliferative phase).
- Directly ovulation itself.
- Luteal (secretory) phase.
The beginning of the menstrual cycle is considered critical days. At this time, the uterus is cleared of the endometrial mucosa rejected as a result of a pregnancy that did not occur. Along with the menstrual blood, dead cells of sexual function come out of the body.
After the critical days, the follicular phase begins. There is an active preparation for a possible pregnancy. The follicles in the ovaries begin the process of maturation. One of them will acquire maximum volumes, and an egg cell will come out at the right time.
The maturation of the follicles is controlled by hormones produced by the pituitary and hypothalamus.
In the middle of the cycle, due to the increase in the level of the Latinizing hormone in the woman's body, the eggs come out of the follicles - ovulation occurs. The ovaries are heavily producing estrogen. This moment of the cycle, the most suitable for conception.
This important period for an organism lasts about one hour. This time is about the same for all women. Most scientists agree that after leaving the follicle itself, the germ cell can be fertilized within 24 hours.
During this period, the fallopian tubes, due to the villi, tighten the egg cell, the level of the hormone progesterone increases in the blood, the uterus prepares for pregnancy.
How to know when an egg comes out of the follicle
The period when the reproductive cell leaves their follicle is called ovulation. Its duration is about an hour, and after its onset, the woman's body is ready for fertilization. The basal temperature rises.
Ladies are trying to calculate the duration of this process: some in order to determine the optimal period for conception, others, on the contrary, not to get pregnant.
One of the most common methods for calculating ovulation is calendar. For example, the duration of the menstrual cycle is 28 days. It is known that ovulation occurs in the middle of the cycle, respectively, it will be 14 days from the first day of menstruation. It is most likely to become pregnant 2 days before and 2 days after this process, due to the fact that the vital activity of sperm cells is higher.
But when using the calendar method it is very important that the menstrual cycle is regular.
The exit of the genital cell from the follicle can also be determined by the symptoms accompanying this process.
When the egg is ready for fertilization, the following signs are observed in the woman's body:
- discharge from the genitals become viscous and become dull in color,
- выделения становятся обильными,
- могут появиться кровянистые мажущие выделения,
- иногда возникает боль внизу живота в виде спазмов,
- происходит вздутие живота,
- появляются тошнота и головокружение,
- растет либидо.
More accurate methods for checking the occurrence of this process are:
- Check basal temperature.
- Ultrasound of the ovaries.
- Test from the pharmacy.
Basal temperature is measured very simply. Every day, before getting out of bed in the morning, it is necessary to measure the temperature in the rectum and record your indicators. So that the result was as accurate as possible, it is necessary to make as few movements as possible. A sharp increase in basal temperature by 1 degree and will indicate the onset of ovulation. In this method, regularity is very important.
Ultrasound examination of the ovaries will accurately show the bursting follicle. True, this procedure is expensive compared to other methods, but also the most accurate.
Special test for determining ovulation can be purchased at the pharmacy. The first test is recommended to be done five days before the expected day of this process. One of the tests done in the following days, will show the day most suitable for conception.
What happens in case of successful fertilization
The last phase of the menstrual cycle is called luteal, it continues from the moment of ovulation until the end of the menstrual cycle, that is, the onset of critical days.
After the release of the egg through the pipes in the direction of the abdominal cavity, the follicle, which she left, reincarnates into a yellow body. This gland produces the hormones estrogen and progesterone, which help prepare the uterus for the expected pregnancy.
After fusion in the fallopian tube of the germ cell with the spermatozoon, the zygote with the help of villi moves into the uterine cavity. It takes about 12 hours from the penetration of the sperm into the germ cell to the fusion of their nuclei. As a result of crushing the zygote, a fertilized egg is created, which is then attached to the wall of the uterus. Under the influence of these processes, hormones are produced that contribute to the maintenance of pregnancy.
The maturation of the egg in a woman
The process of maturation of the egg (YAC) from a biological point of view, is very complex. They form in the body of the girl when she is still in mother's womb, that is, long before her birth. Before puberty, they are at rest, and a certain part of them stops its development and dies. When the first menstruation occurs, individual eggs begin to mature and prepare for potential fertilization.
Ripening process eggs by woman by day:
- before puberty, the nuclear centers are at rest (some of them die for natural reasons or under the influence of certain factors),
When the egg matures after menstruation?
If a menstrual cycle is 28–30 days, in most cases the egg begins to mature on the 14th – 16th day of the cycle, but this indicator depends on the individual characteristics of the organism, ovulation can be late or early (the egg can mature immediately after the menstrual period).
For a woman planning a pregnancy, it is necessary to know exactly on what day the egg matures. Because only during this period can to conceive. Methods for determining the day of maturation of the egg:
- if measured daily basal temperature over several months and record the data, it is possible to determine the day of ovulation by raising indicators (this technique may give inaccurate results, some diseases of the reproductive organs or infections of the reproductive system can change the baseline temperature, and the symptoms do not cause discomfort),
How many eggs mature in one cycle (per month)?
In most cases, during one woman ovulation one egg maturesHowever, there are exceptions.
Sometimes in the female body can occur two ovulatory process after a short time. There are cases when two follicles mature in one cycle.
This is not a deviation from the norm. When a woman matures several JCs, the chances increase. multiple pregnancy.
Nuances that are important for women to know:
- if during one cycle one NRC matures, then the conception of one child will occur,
There is also syndromeempty folliclein which there is no egg. If such situations occur once a year, they are not a cause for concern. With the constant lack of maturation of the NRC, infertility occurs.
Information about the process of maturation of the NCC is necessary for women not only during the planning of pregnancy, but also to exclude unwanted conception. Unlike male sperm, which is able to maintain its activity up to 5-7 daysA female egg can only be fertilized during the day. If you know your body and all the processes that occur in it, then unexpected conception can be prevented.
What is an egg
This unique cell in its structure and function. It contains exactly half of the chromosomes, which, when merged with the male reproductive cell, gives rise to a healthy, full-fledged child. It is rich in nutrients. This allows new life to comfortably develop up to the moment when the fertilized egg penetrates the uterine wall.
Each lady nature counts the individual number of female germ cells. Their number is tens of thousands. After the onset of puberty, a certain number of them mature every month. For this reason, in the ovary every month they are getting smaller. After the onset of 35-40 years of age, this number becomes negligible, getting pregnant is becoming more difficult.
When the egg matures
The duration of menzis for each woman is individual. Most often, menstrual bleeding begins to bother the representative of the weaker sex after 28 days from the previous one. The egg cell ripens strictly in the middle of the cycle. Performing simple mathematical calculations, it is not difficult to determine that ovulation in this case occurs on average 14 days after the menstrual period.
However, to say for sure that the egg comes out exactly on the 14th day will be wrong. Exit the egg from the follicle may during the period from 13 to 15 days of the cycle. This is theoretically. Life makes its own adjustments to all processes. Under the influence of stress, transferred infectious diseases, ovulation can happen twice a month. There are cycles without ovulation.
As the egg matures after menstruation
Menstruation in the body of a woman occurs under the action of a number of hormones. Manages their release several central endocrine organs (hypothalamus, pituitary). The maturation of the egg is influenced by the brain.
The whole process of maturation of the female germ cell is usually divided into three phases:
- follicle development phase
- luteal phase.
In the ovaries in the womb some amount of eggs is laid. After some period of time after the onset of menstrual bleeding (on average, according to research, for 3-5 days) several female germ cells begin to develop simultaneously. Usually their number reaches two dozen.
Not many follicles are able to reach maturity and give rise to a new organism. As a rule, most of them suspend their development, and only one or a few develop more actively.
Nature determines for each woman the number of eggs that can reach maturity while one menstrual cycle lasts. This is the main reason why in one family only one child is always born, and in the other - a woman can simultaneously become pregnant with two or three children.
In the middle of the cycle in the body of a woman increases the content of luteinizing hormone. This substance stimulates the rupture of the follicle and the release of a mature egg into the abdominal cavity. This is how ovulation occurs. From this moment comes the most favorable period of the cycle for the conception of the heir.
A mature egg is not destined to long wander in the abdominal cavity. It is picked up by the villi of the fallopian tubes and tightened inside the tube. In place of a bursting follicle, the so-called yellow body develops. In the blood during this period, the content of progesterone increases, the inner layer of the uterus grows, loosens and prepares to accept a fertilized egg.
How long does ovulation last
This period for all ladies lasts approximately the same time. On average, the duration of ovulation is no longer than an hour. Most scientists agree that the egg remains young, active and able to merge with sperm exactly one day after it leaves the follicle.
How to determine the onset of ovulation
The most sensitive young ladies feel the onset of ovulation on a subconscious level. To say for sure that the time “X” has come is possible due to a number of signs:
- vaginal discharge becomes viscous, turbid,
- their number increases
- discharge may become bloody,
- discomfort, sometimes pain, similar to contractions in the lower abdomen,
- belly swells
- craving for unusual food
- increased sexual desire.
However, this is not entirely reliable. In different women, the described symptoms appear a few days before the ovulation date and may last for some time afterwards. The situation will save:
- basal temperature measurement
- Ultrasound of the ovary (makes it possible to see and measure the follicle),
- ovulation test.
This is a fairly easy-to-follow procedure. It is necessary for a woman to measure the temperature in the rectum and just fix it in the diary just daily before getting out of bed in the morning. A jump in temperature up by 1 degree will indicate ovulation occurred. The main thing for the most accurate measurement results as little as possible to move before the procedure.
How many days after menstruation expect ovulation? This question is asked, in two cases:
- to make a better period and get pregnant
- to avoid unwanted pregnancy.
Focusing on the date of ovulation in a situation where you want to get pregnant is not quite right. It is better to start trying for a certain period before the expected day of the release of the egg from the ovary and continue to achieve its goal for some time after this point.
Focusing on the day of ovulation to avoid an unwanted pregnancy is also not worth it. First, sperm are able to maintain their mobility and activity for a relatively long time. Secondly, it is not excluded that it is possible to get into a cycle in which several eggs can mature within a certain period of time.
When ovulation occurs - how many days after menstruation?
If a woman knows the duration of her menstrual cycle, it will help her when planning the conception or the sex of the child, protect her from unplanned conception, and also help to track whether ovulation occurs after menstruation at all. If this does not happen, the woman is prescribed treatment.
The opinion that the ovulation period is normal should come to the middle of the cycle is not absolutely true. The time of rupture of the follicle depends on the duration of the cyclic process, which is individual for everyone. Sometimes women accelerate the release of the egg involuntarily, early ovulation can be triggered by:
- weight lifting
- swing press,
- the use of sage broth in the follicular phase,
- discontinuation of oral contraceptives.
The duration of the menstrual period is measured from the first day of blood until the last day of the next critical day. Follicle nucleation occurs on the day of the beginning of the menstrual flow, then it forms an egg cell. On the day of its release, the spermatozoon should get into it, if this does not happen within 24 hours, conception will not happen. Therefore, when planning, it is important for parents to know on which day after their monthly ovulation occurs.
For this it is customary to use several methods:
- calendar calculation
- basal temperature measurement
- use of tests
- ovulation symptoms.
Now we will take a closer look at each of the methods for calculating the day the egg is released.
The majority of the fair sex, the menstrual period lasts 28 - 35 days. The release of the egg occurs approximately 2 weeks before the onset of menstrual flow. If we take into account the cyclical nature of 28 days and subtract 14 from it, then it will be 14. This figure means on what day after the monthly ovulation occurs.
To find out the length of your cyclic period, you need to have a calendar, which will mark the start of critical days for more than one month. Further, as described above, it is necessary to subtract 14 from the number of days of the cycle and determine the desired day.
These calculations can not give 100% result, because in practice, a low percentage of women has a regular cycle. This is due to many reasons:
- emotional condition,
- physical exercise,
- hormone levels
- the presence of disease and so on.
To confirm her calculations, in addition a woman can measure rectal temperature.
Basal Temperature Measurement
It is necessary to measure the temperature every day immediately after waking up, its fluctuations range from 36.2 to 36.9 degrees, a jump in degrees to 37 indicates the beginning of a favorable day. Before using a thermometer, it should be oiled or vaseline, then turn on its side, enter into the rectum by 1 - 1.5 cm and hold for 5 - 7 minutes. It is necessary to start measuring rectal temperature and recording the results daily, at the same hour, immediately after the end of the menstrual blood.
The method of measuring basal temperature to determine the day "x" is an ideal method for an unspecified cycle.
Test strips are recommended to use, after determining the duration of the cyclic period. If it is regular, then 17 days should be taken from its duration, 14 of which is the approximate time of the onset of ovulation and 3 days are taken with a margin, since the maximum lifespan of an egg cell can reach 3 days. In the case of an irregular cycle, it is necessary to subtract 17 from the shortest period, this date will also be considered approximate.
If the cycle is not regular, then the woman should contact a specialist to find out the cause, as this may be associated with some diseases.
So, in order to understand when exactly to use the dough we use an illustrative example, we take into account the cycle of 29 days and the beginning of the monthly 4th day:
- From 29 we need to subtract 17 and get 12.
- Next you need to take 12 days, from 4 numbers, it turns out 16.
- From the day we start, we start testing every day, ovulation is expected on the 18-19th number, on these days there should be 2 distinct strips on the test.
Symptoms approximation of ovulation
The ejection of the egg can be felt as a result of the production of a large amount of hormones in a woman:
- body temperature rises
- pain in the lower abdomen appears,
- changes in cervical mucus,
- the attraction to the partner increases,
- discomfort appears in the chest.
Sometimes, during the period of ovule release, a brown fluid is released from the woman's womb, the reason being a follicle rupture or estrogenic excess. Such manifestations are detected several hours before the release of the egg and continue for 2 days.
Small intermenstrual bleeding is observed in many, a similar phenomenon is considered normal in most cases, sometimes bleeding is caused by:
- oral contraceptives or rejection of them,
- depression and other things.
When brown secretions appear, a woman needs to rest more, not be nervous and get rid of depression. If you apply the above methods and based on your own feelings, you can accurately determine the day of ovulation.
Ovulation with a cycle of 7-19 days
The girl's menstrual cycle from the moment it began can be established within 12 months, during this period they can be irregular, which is not considered pathology. If menstruation is not restored after 12 months, you need to visit a specialist.
A single abnormal cycle is not considered dangerous and does not require medical advice.
The menstrual period is considered short if its duration does not exceed 21 days. In this case, changes occur with the nature and volume of blood. Menstruation becomes profuse and the woman begins to experience pain during them.
The formation of the egg mainly occurs earlier, with a cycle of 21 days, ovulation is possible on day 7. It should be recalled that the maturation of the follicle can be late or early in any cycle. For example, if it lasts 28 days, then ovulation is possible on the 17th - 19th day of the cycle, with early maturation on the 7-10th day.
Ovulation with a cycle of 20-29 days
A cycle of 28 calendar days is considered to be average, monthly deviations from the norm are permissible, but they should not have a difference of more than 3 days. Abundant menstruation, more than 80 ml per day and the duration of critical days longer than a week can also be considered as the reason for going to a specialist.
The calculation with the average duration is not difficult to make, if the cycle lasted 28 -29 days, then ovulation will appear 14-15 days. Если цикл составил 27 дней, тогда овуляция свершится на 13 день, овуляция при 26 дневном цикле приходит к 12 дню, овуляция при цикле 25 дней на 10 – 11 сутки и т д.
Ovulation on the 20th day of the cycle or later is possible before menopause, if the woman becomes pregnant, miscarriage or birth defects of the baby is possible.
Ovulation with a cycle of 30-35 days
A menstrual period of up to 35 days, despite its duration, is considered normal if it is regular. The calculation is made in the same way as the earlier subtraction method, if the cycle is 35 days, then the auspicious day should come on 21 days, with a cycle of 31 days ovulation is expected on day 17, ovulation at the 30 day cycle falls on day 16.
If the menstrual period exceeds 35 days, this is considered a reason for going to a doctor. A woman in no case can not self-medicate, it can lead to bad consequences.
What time of day does ovulation occur and how many days does it last?
At what time of day the follicle throws out the egg is not easy to answer, because each organism is special. But in order to increase the chances of fertilization on this day, the couple are recommended to have sexual intercourse in the morning and evening. After exiting the follicle, the egg begins to move to the uterus through the tubes. If she encounters a spermatozoon on her way that manages to get inside, she will become fertilized. Next, the ovum must fall into the uterus and attach to the endometrium, then pregnancy begins.
The ovulation cycle is short, it is 12 - 36 hours, on average, it is considered active during the day after the release. If during this period the merger with sperm did not occur, it will die and come out with menstrual bleeding. When calculating for conception, it is necessary to take into account the life expectancy of spermatozoa, men live for 23 hours, women for about 5 days.
What happens after ovulation?
Every woman knows how ovulation and menstruation are related. If fertilization has not taken place after it, then critical days will begin, if it happens, then menstruation will not come. A woman will begin a pre-implantation period, which lasts 4–5 days, during which time the fertilized egg moves into the uterus. Its transportation is facilitated by:
- contractile movement of the smooth muscles of the fallopian tubes,
- motility of epithelial cilia,
- sphincter relaxation between the uterus and the fallopian tube,
- increase in hormones progesterone and estrogen.
During this period of time, intracellular division occurs, before entering the uterus, 16 to 32 cells form in the embryo. Fastening of the ovum will come in 24 hours, until that time it floats freely in the uterus. When the sperm reaches the day “x”, fertilization occurs immediately after the release of the egg.
Does ovulation happen right after your period?
Calculating the terms of conception, doctors exclude its possibility immediately after the critical days. However, ovulation immediately after menstruation is quite possible, and the reasons for this may be:
- short menstrual period, ovulation with it may come on the 9th day of the cycle or earlier, while not taking into account the duration of bleeding,
- duration of critical days (more than 7),
- lack of stable cycle
- formation of more than one egg.
In the latter case, the maturation of the second egg happens in the female body, immediately after the first follicle bursts. Thus, the critical days end, and a new ovulation cycle begins immediately. This can happen in women who are predisposed to having twins or triplets.
Among other things, early ovulation may occur due to menstrual failures, which can be triggered by:
- sharp climate change
- weight gain or weight gain
- use of certain drugs
- hormonal disruptions
- postpartum periods and abortions,
- physical exhaustion,
- any diseases.
The definition of ovulation, regardless of whether it is early or late, is carried out by the same methods: by symptoms, GD temperature, test strip, ultrasound, and the calendar method.
Does ovulation occur every month?
The formation of the egg is due to hormonal influence, the release of which is carried out by the adrenal glands, the pituitary gland and the endocrine system. Follicular maturation can occur in one or both ovaries. Follicular rupture occurs when it reaches a large size. The ovum, ready for fertilization, is washed away with liquid into the abdominal cavity.
Normally, the ovulatory period should be monthly, but its absence is permissible, but not more than 2 times in 12 months. Anovulatory periods are triggered by the same factors that have an effect on the regularity of the cycle. If they are caused by any diseases, then the body automatically blocks the reproductive system, making it clear that the body is now weakened, this is not the best time for conception. For anovulatory periods, doctors refer the patient to a comprehensive examination, since they can be caused by serious diseases.
In order for a woman to understand the failures of the reproductive system, she must know the signs of periods without ovulation, and they are:
- the absence of protein secretions
- constant periods of menstruation (critical days may be absent for several months),
- profusion or scarcity of blood discharge,
- basal temperature less than 37 degrees (relevant for those who monitor its performance daily).
Anovulation can also be determined by the absence of pregnancy, despite regular, unprotected sex. It is the last signs that lead patients to see a gynecologist. Often, anovulation is accompanied by amenorrhea or oligomenorrhea, characterized by the absence of menstruation or their scarcity.
