For successful conception, a woman must approximately guess on what day ovulation occurs. In order to find out what day ovulation occurs, you must monitor and correctly interpret the signs of your body. How to do this you ask? Let's sort it out with you!

Let's make a small disclaimer. Each woman is special and individual, therefore, ovulation will occur for each woman on a different day of the cycle. Even if you and your friend have equal cycles, say 30 days each, this does not mean that you and your friend will ovulate on the same day. The same applies to you. If you determine that ovulation this month occurred on the 14th day of the cycle, this does not mean that in the next cycle, on the 14th day, you should ovulate again.

Why is that? You ask. But the fact is that your body has very complex mechanism work, and this mechanism can be influenced by many factors, and in in this case for ovulation. This could be stress, hypothermia on the street, spicy food, shift climatic conditions, strong physical exercise or a certain diet. Therefore, in order to determine what day ovulation will occur, you need to carefully monitor and know your body.

If you have a regular, established cycle, then using methods to determine ovulation and paying attention to your body's signs, you can guess on what day of the next cycle you will ovulate. But let’s say right away that for many women, ovulation occurs approximately between 11 and 21, the day after last day menstruation, or 12 -16 days before the next menstrual period.

Is it true that ovulation occurs on day 14?

You can hear from many women, including doctors, that ovulation occurs on the 14th day of the cycle if your cycle is 28 days long. Unfortunately, this is a myth. Above, we have already discussed that ovulation is determined by many factors, and on what day ovulation occurs depends, among other things, on them.

How long before I can get pregnant?

After the egg is released from the follicle, it can be fertilized within 24-48 hours. But, sperm can live in a woman's reproductive tract for about 3-5 days, so your fertility is typically 5-6 days. Let's say you know that you will ovulate in 5 days. So, having sexual intercourse during this time, for example 1-2 days before ovulation and on the day of ovulation itself, your chances of conceiving are very high. Of course, you can have sexual intercourse 5 days before ovulation, but then the chances of fertilization drop sharply.

Can ovulation occur during menstruation?

If a woman has a regular cycle, then the chance that she will ovulate during her period is very low. However, as we said above, each woman has her own unique hormonal background, and thanks to this, there is no need to deny that ovulation cannot occur during menstruation. Of course, the likelihood of this is very, very small.

Can ovulation occur immediately after menstruation?

It all depends on how long your cycle is. For example, if you have a 20-day cycle, from the first day to the next first day, and your periods last 7 days, then there is a chance that ovulation will occur immediately after your period. This may happen because it has already been said that ovulation occurs 12-16 days before your next cycle, in this case, ovulation may occur on days 7-11.

Is it possible to get pregnant if you have sex during your period?

Sperm can live in a woman's reproductive tract for about 5 days. If you ovulate immediately after your period, and you had intercourse a few days before the end of your period, then pregnancy can occur.

Why is it important to know what day ovulation occurs?

Of course, many women want to know when they ovulate.. Knowing or guessing the days on which it will occur will help ensure birth control. Knowing your ovulation days can help you:

Track your menstrual cycle. Tracking your menstrual cycle will help you not to be caught off guard when your period starts.

Increase your chances of conceiving. Knowing the day of your ovulation, and having contact on, you thereby have a high chance of conceiving.

Preventing pregnancy. Women who are sexually active and do not want to have children yet can control their sex life. If you do not want to have children yet, you need to abstain from sexual intercourse for several days before ovulation and during ovulation itself. This will reduce your chances of conceiving.

Signs of ovulation

Breast tenderness: Before and during ovulation, your breasts become tender. As a result, it may become painful. Any strong touch can cause pain.

: Many women experience pain in the lower abdomen. This is due to the fact that when the egg ruptures the follicle, the woman can feel it as acute pain lower abdomen. This pain can last from a few minutes to several hours.

Changes in the consistency and shape of the cervix: the cervix will change its consistency, it will become softer and more open. It will also change shape and position.

Increased cervical fluid: A few days before ovulation and during ovulation itself, you may notice that your cervical fluid has become larger and more stringy. At this time, the cervical fluid has a very characteristic color- raw egg white.

In addition to changes in your body, there are certain methods that will help you better know when you are ovulating.

Menstrual cycle schedule

Many women choose to chart their menstrual cycle in order to determine what day they ovulated. This chart is good because thanks to it, you can predict your ovulation in the next cycle. Mark the first day of your period on your calendar. This is your start of the cycle. In your next cycle, you will also record your first day of your period. Now count the number of days between them to find out the length of your cycle. To determine when you ovulate, subtract 14 days from the first day of your cycle. Be careful! This method won't give you the exact day you will ovulate, but it can give you a good idea of when you might ovulate.

It would seem that a young woman can get pregnant quickly and effortlessly. Especially if your periods are regular, your health indicators are excellent, and your spouse dreams of a child no less than yours... But how to calculate what day of ovulation on a cycle of 28 or 30 days in order to finally catch this elusive egg and conceive a long-awaited little life?

The mechanism of conception is both simple and complex. Nature designed it in such a way that a woman is given the opportunity to become pregnant every month. However, some women easily take advantage of this opportunity, even planning the date of their upcoming birth. And others, no matter how much they want, cannot get pregnant. What's the matter? Maybe you should just make a simple calculation and figure out a good day for conception?

Normal menstruation is a periodic phenomenon, repeating from month to month, and it is not for nothing that the interval between the beginning of the previous and the beginning of the next menstruation is called a cycle. It is this cyclicality that allows you to calculate the days when you can get pregnant. And also safe days when unprotected lovemaking is not undesirable consequences. A natural biological method of contraception is based on this calculation. "Classical" female cycle is 28 days. A duration of 30 days is also the absolute norm.

Around the seventh day of the cycle, the dominant follicle is determined - it will grow for about another week and then rupture, releasing a mature egg. The egg will begin its journey through fallopian tube to the uterus, maintaining viability for about a day. If sexual intercourse occurs at this time, and sperm are given the opportunity to penetrate the cervix (express methods of contraception are not used, the woman does not rush to the shower immediately after ejaculation, etc.), one of the sperm that reaches the fallopian tube will fertilize the egg, and conception will occur.

As a rule, symptoms of ovulation do not appear externally, but some women note nagging pain in the abdomen, changes in well-being, and engorgement of the mammary glands. All these signs are called ovulation syndrome. However, you should not trust such “tips” entirely.

How to define “these days”

Ultrasound of follicles;
blood test to determine the concentration of luteinizing hormone (ovulation hormone);
maintaining a basal temperature chart;
ovulation test.

Every woman can independently calculate ovulation at home by measuring her basal temperature daily or using a test. Test diagnostics are done repeatedly, starting from about 11-12 days of the cycle. The mechanism of action of the test is simple: the reagent applied to the strip strip is sensitive to luteinizing hormone, which controls the release of the egg.

On the eve of ovulation, the test shows clear 2 stripes. On average, on the fourteenth day of the cycle, the test will show positive result- this means you can’t waste precious time: the egg lives for about a day or two! And if you miss the opportunity, you will have to wait at least another month for the favorable moment.

Keeping a temperature chart and buying tests - all this requires a certain discipline and financial investment. Or you can simply calculate the day of ovulation, knowing the start date of your last menstruation. How to do it?

Useful formulas

The arithmetic of calculating ovulation is simple. If the cycle is 28 days, then we divide 28 in half, remembering that ovulation occurs in the middle of the cycle, and we get the number 14. This means that with a 28-day cycle, ovulation occurs on the 14th day from the start of the last menstruation. For example, the last period came on January 5, which means that ovulation will occur in 14 days. It will be January 19th - the most successful day for conception. However, minor disruptions are possible even in the body of healthy women, and the egg may be “delayed” in being released or released earlier. Plus, don’t forget that sperm have their own “ideas” about what is considered life expectancy. So, if the egg is given 12 to 24 hours, the sperm can survive up to a week!

Textbooks on gynecology describe a simple way to calculate the monthly time of fertility (ability to conceive).
Beginning: divide the number of days of the cycle in half and subtract average term life of sperm: 28:2-4= 8. Therefore, conception is possible already from the 8th day of the cycle.

End: divide the number of days of the cycle in two and add the lifespan of the egg (1 day) and a possible error of 2 days (if the definition is approximate) - 28:2 + 1+2 = 17. Consequently, the ability to conceive remains until the seventeenth day of the cycle.

For a 30-day cycle, the calculation is similar. The fertile phase begins on the 9th day of the cycle, and its end on the 18th day.

Why is ovulation delayed or comes earlier?

Despite the apparent simplicity and accessibility of calculating a day favorable for pregnancy, there may be some nuances here. Even with regular cycle Ovulation can occur not just a day later or a day earlier - these deviations from the norm can also be longer. For example, the concept of early ovulation is widely known - this is premature ripening eggs. This phenomenon can occur for a number of reasons, among which the most common are:

failure in the hormonal system;
stress;
treatment with drugs that affect hormonal levels;
sports overload;
establishing a cycle after childbirth or abortion, etc.

When it happens premature ovulation, you can accurately calculate her day at home only by measuring basal temperature or using a test. As practice shows, early ovulation can occur immediately after the last day of menstruation, and therefore, when asked whether it is possible to get pregnant on the 6th day of the cycle, an experienced gynecologist will answer positively, noting that, although unlikely, this option is also possible.

And the opposite situation also happens, when ovulation occurs later than the middle of the cycle - we're talking about about late ovulation. Its onset is possible on the 18th and 21st day of the cycle, and even later. There are many reasons for late ovulation, among which the most likely are: hormonal disbalance, stressful situations, sudden loss weight, illness genitourinary system etc. In this case, it is not easy to keep track of the days when the egg is released; as usual, they will help you. basal method or using ovulation tests.

When to take a pregnancy test

With a cycle length of 28 days (or 30 days), when ovulation is clearly defined and a favorable day for conception has not been wasted, you can stock up on pregnancy tests. These little diagnosticians are able to show its onset with a high degree of probability at home.

On days 7-10 after ovulation, the fertilized egg is implanted into the uterine cavity, attached to its wall, and the production of hCG (human chorionic gonadotropin) - the pregnancy hormone - begins. The reagent applied to the pregnancy test strip is sensitive to this hormone.

The concentration of the hormone sufficient for its recognition by the test increases 12-13 days after ovulation. Thus, good test may show a positive result a day or two before the delay. The optimal time is considered to be at least from the first day of the delay. The test is carried out with a morning urine sample, however, if there is pregnancy, the hCG concentration will be sufficient at other times of the day.

Ovulation is required condition for natural conception. Learning to monitor it with a regular cycle of 28 days is not only possible, but also necessary to control own health and planning a long-awaited pregnancy.

Even during the period of intrauterine development, each girl develops a millionth supply of eggs, which in the future, after puberty, will actively work for procreation. With the onset of menarche (first menstruation), every month from this huge army of female reproductive cells, one and only one will mature. The follicle that stores it begins to enlarge at this time, which is why gynecologists call it dominant. When the egg is completely ready for fertilization, the follicle ruptures and releases it. This phenomenon is called ovulation (ovulla in Latin means egg).

Normally, ovulation occurs regularly, which indicates good reproductive health women. This regularity is different for each of us: for some every 25 days, for others - every 32 days. Moreover, it may not be permanent.

Divides the menstrual cycle into two phases - follicular and luteal. But the duration of each of these phases is different for all women, as, in fact, is the duration of the cycle itself. For most women, the menstrual cycle lasts on average 28-32 days, although longer or shorter options are possible. Ideally, ovulation occurs in the middle of the menstrual cycle - on days 12-15. But it is impossible to say exactly when ovulation occurs in a particular woman. Plotting basal temperatures for at least 4 months in a row allows you to indirectly judge the day of ovulation. But it is quite labile and can move in any direction.

Ideally, with a 28-day cycle, ovulation occurs on the 14th day from the start of the last menstruation and 14 days before the start of the next, that is, exactly in the middle. However, the ideal is rare in nature. Experts say that on average, ovulation occurs in different women occurs between 11 and 21 days from the first day of the last menstrual period, or between 12 and 16 days before the next one.

It should be noted that ovulation can shift in time to different cycles. If in the last cycle a woman ovulated on day 15, this is not a guarantee that the scenario will repeat in the next cycle.

Ovulation occurring month after month is considered a sign normal functioning the female reproductive system and a woman's full ability to conceive children. However, within normal limits there is also a “break” in the maturation of the egg 2-3 times a year, that is, out of 12 cycles, ovulation can occur, for example, only in nine. If ovulation does not occur systematically, then we are talking about a violation of reproductive functions, and a woman who wants to get pregnant will have to seek help. medical care. There can be many reasons for anovulation.

In some cases, two ovulations occur within one menstrual cycle. This happens against the background of some kind of shock or stress; women are more susceptible to such double ovulations, sex life which are not regular.

If you want to find out when you ovulate, you need to use at least one of the methods for determining ovulation. But it is not recommended to use it as a contraceptive method: its reliability is very low.

Especially for Elena Kichak

Any woman needs to know what day of her cycle ovulation usually occurs. This will help plan your pregnancy. Moreover, you can try to choose the gender of the child if you know exact days for conception.

It is ovulation that makes it possible to become a happy mother, so you should understand what day of the cycle it begins on. If female body healthy and working like clockwork, problems with calculations the right day will not arise. Otherwise, you will have to resort to the help of specialists.

It happens that a woman has calculated the day on which the long-awaited ovulation should begin, but it does not come. This means that there is some kind of malfunction in the body and you need to urgently consult a doctor. Let's take a closer look at this issue.

Every woman needs to know

When to expect this phenomenon

After ovulation, a mature egg leaves the follicle to merge with a sperm. He, in turn, lives a maximum of 7 days, and usually no more than three. Life cycle eggs is 12-24 hours. Therefore, you need to calculate on what day of the menstrual cycle a woman ovulates.

There are several main points:

the menstrual cycle should be counted from the first day of menstruation of the past month to the first day of the next menstruation;
the egg may not mature if there is any disruption in the woman’s orgasm, the problem will have to be solved by an experienced gynecologist;
you can start counting on what day of your cycle the long-awaited ovulation should occur, but your period does not come, in this case you also need to contact a specialist.

If there is no suitable time

You can scrupulously calculate on what day ovulation will occur when the cycle lasts 27-29 days, but it never comes. This usually occurs due to problems in the hypothalamic-pituitary-ovarian axis. Dysfunction is caused by:

genetic factor;
inflamed genitals;
stress.

It could also be due to any infection, affecting menstruation, or climate change when traveling on vacation. Scientists' research has led to an unexpected conclusion. It turns out that it doesn’t matter what day ovulation occurs, if the cycle is 25-26 days, the egg will be released from the ovary only if the woman has at least 18% body fat. Estrogen accumulates in them and the androgen hormone, which is responsible for the process, is converted. Thus, a lack of hormones leads to serious problems: absence of menstruation. However, a similar thing can happen if a woman has overweight bodies.

Testing for sexually transmitted infections

It also happens that a woman is confident in her health, so she calculates on what day of her menstrual cycle the long-awaited ovulation will occur, but it does not occur. There is nothing to worry about here, because this phenomenon occurs even in absolutely healthy women. The number of such anovulatory cycles increases every year. For example, up to 30 years old their number is 2-3 per year, and for 40 years old it is already 4-8.

In any case, you need to find out the reason for what happened. It is necessary to undergo examination by an endocrinologist or gynecologist to get advice or competent treatment. Most likely you will have to:

undergo an ultrasound examination of the ovaries, pancreas and thyroid glands;
take tests for the presence of sexually transmitted infections, hormone levels;
take blood and urine tests.

If ovulation is not observed for more than a year, although sexual activity occurs regularly, treatment is prescribed. Doctors usually prescribe the medication Clostilbegit. This medicine includes hormones that stimulate the desired process.

The medication is quite effective. According to statistics, 15% of women became pregnant during the first month, and another 50% in the second month.

You should not carry out treatment yourself. Therapy should proceed under the vigilant supervision of a physician so that he can monitor the body's reaction. Otherwise there is a risk of developing serious complications. Before prescribing a medication, a woman needs to undergo an examination and be sure to take several tests:

blood test to check immunity to rubella;
cross-country ability fallopian tubes;
cultures to detect gardnerella, mycoplasma, trichomonas, ureaplasma, chlamydia, candida;
smear for oncocytology;
analysis for hepatitis group C, B;
test for HIV, syphilis.

During the appointment, the doctor tells the patient on what day of the menstrual cycle the process of ovulation stimulation should begin. Usually the drug is taken from days 5 to 9 of the cycle. If additional stimulation is carried out using Puregon, then from 3 to 7 days.

Therapy with these drugs should not exceed 6 courses in a row. Otherwise, ovarian exhaustion may develop, which is dangerous due to early menopause. When treatment does not bring the desired result after the third course, the doctor usually reconsiders the treatment methods.

Premature release of the egg

Sometimes ovulation occurs ahead of time. This happens for a number of reasons.

Various pathologies.
Strong physical activity.
Climate change, lifestyle change or severe stress.
Sudden weight gain or loss.
Drug treatment.

These factors are not always noticeable to a woman. She continues to live as before, but a hormonal imbalance begins in the body, which can affect the duration of her period, as a result of which the egg is released earlier than expected.

Long-awaited pregnancy

This shift in the body will not affect your health in any way unless you are planning to become pregnant and are not using calendar method for contraception. However early exit eggs may be a surprise in several cases:

IVF was prescribed, so medications must be taken strictly after ovulation;
you think it is impossible to conceive a child after menstruation.

If you have a cycle of 33 days or more, it is very important to calculate what day ovulation begins so as not to miss such an important event. To do this, you need to closely monitor your well-being and body signals. Need to.

Measure your basal temperature regularly. It is best to measure it at the same time and record the readings in a notepad.
Monitor vaginal discharge.
Conduct special tests, which can detect a surge in luteinizing hormone.
Conduct an ultrasound examination to assess follicle growth (folliculometry).
Take tests to monitor hormone levels (FSH, LH, progesterone, estradiol).

Even from the prenatal period of development, the body of the future woman is preparing for procreation. Throughout her life, a huge number of eggs will be formed in her body. From the first menstruation onwards every month large quantity Once formed, only one oocyte will mature. Medical workers this egg is called dominant. During the process of maturation, the follicle, consisting of an egg and a membrane, gradually increases in size, eventually it ruptures and the egg ends up in the fallopian tube.

Let’s now figure out when ovulation occurs. This depends on many factors. If a woman reproductive system works properly, the ovulation process is stable and regular. But its frequency in any case directly depends on the menstrual cycle.

Ovulation occurs in the middle of the menstrual cycle (plus or minus two days), and its duration is different for all women. Therefore, it is only possible if you know the length of your cycle, and then this will be very approximately. With irregular periods, as you understand, the task becomes even more complicated.

So, is there a way to know exactly when the next ovulation will occur? Yes, such a possibility exists. You can buy special ovulation tests at any pharmacy. It doesn’t matter whether they are disposable or reusable, the fundamental principle of their operation is the same - determining the concentration of luteinizing hormone in the urine. Immediately before ovulation, its level reaches limit values, and the test will show it. In order not to miss this moment, start checking for ovulation a few days before the middle of the menstrual cycle. If you are not sure about its duration, use the test from the 5th day from the start of your period.

If the test does not show ovulation during the expected period, do not rush to sound the alarm. Even healthy woman It is not necessary that every cycle involves ovulation. Now, if this happens again for several months in a row, then you definitely need to find out the reasons, and you can’t do it without the help of doctors.

How long does ovulation last?

The process of releasing a mature egg from the follicle usually lasts no more than an hour. When asked the question of how long ovulation lasts, the concepts are most often confused and mean the time during which the egg retains the ability to fertilize. After ovulation, nature allows about a day for the fertilization of the egg.

Why are there at least three days favorable for conception? Everything is explained quite simply. Sperm that reach the fallopian tubes after sexual intercourse remain viable for several days. And if they are there before ovulation, then they simply wait to meet the egg.

During the period when a woman is ovulating, she may experience sensations nagging pain in the lower abdomen, accompanied by viscous vaginal discharge. If measured basal temperature, then the graph will show a fairly significant increase compared to the previous period. Also during this period, most women begin to experience increased sexual desire.
