With a cycle of 29 days, it can come in different ways. Usually this is the 15th day after the onset of menstruation. On average, this cycle is considered long, since it exceeds the standard one by 1 day. In this article, we will figure out how to calculate fertile days and with what methods you can find out the favorable period of conception.
The name of the bleeding justifies itself. The duration of the Lunar is 28 days, this figure is equivalent for a normal menstrual cycle.
However, it is different for every woman. In this regard, you need to know how to ovulate in a particular case.
The concept of the menstrual cycle is the duration from the first days of menstruation to the day before the next.
Science says that the norm is 21-35 days... At the same time, doctors are convinced that a woman's body works without interruption if they come every 25-29 days.
The cycle is divided into two phases:
- follicular where it ripens, and with it and;
- luteal... Its time comes after the release of the LH hormone, that is, after the release of the egg.
The first part of the cycle, equal to 29 days, is individual for each woman, but the second must necessarily last at least two weeks. It is important to understand which ovulation occurs. This process suggests that the follicle bursts, a viable egg preparing for fertilization comes out of it, thereby causing a small wound.
Determination methods
Many women feel that this moment is approaching. If you listen carefully to yourself, you can understand what changes occur in the body on a particular day.
Feels like
So, sensations often speak about the imminent release of the egg. Among them, the following are distinguished:
- , moreover, from the side where the dominant follicle matures;
- discomfort appears inside;
- increased sexual desire;
- taste preferences change;
- are recorded;
- apathy appears;
- observed;
- , excessive emotionality;
- rises;
- appear.
Tests
Pets will help to find out about the onset of ovulation, which determine the level. Let's remind that it is his splash that says that the right day has come. The tests are carried out using strips that resemble the test for. There are usually five in a pack. They need to be done every day, starting on day 10 with a 29-day cycle.
Two stripes are considered a positive result. At the beginning of testing, they may be lighter, but gradually darken.
The downside to this method is that good tests are not cheap.
Basal temperature
Daily measurement of basal temperature is considered a proven and free method. All this is done in the morning, without getting out of bed, rectally. Doctors advise keeping the thermometer close to the bed at all times.
All indicators are recorded in a separate notebook. Based on them, a schedule is built. We can talk about the onset of ovulation when the temperature exceeds 37 degrees.
Important! For the results to be more reliable, you need to draw conclusions based on three cycles. It's hard to say anything for one month.
Perhaps the most accurate method is a specialized ultrasound scan. It is called folliculometry in gynecology. The procedure is painless and quick. A vaginal sensor is inserted into a patient lying on a couch, with the help of which the diagnostician assesses the condition, looks for a dominant follicle, and measures its diameter in millimeters. The positive side is also the fact that the doctor can tell what state the endometrium is in and whether it corresponds to a particular day of the cycle.
This ultrasound must be done in dynamics for several days. At the last procedure, the doctor will tell you the approximate time of ovulation or, by the presence on the screen, will say that it has already occurred. The disadvantage of this method is its high cost. In addition, the effectiveness decreases if the diagnostician does not have sufficient experience.
Any woman needs to know on what day of her cycle ovulation usually occurs. This will help you plan your pregnancy. Moreover, you can try to choose the gender of the baby if you know the exact days for conception.

It is ovulation that makes it possible to become a happy mother, so you should understand on what day of the cycle it starts. If the female body is healthy and works "like a clock", there will be no problems with calculating the desired day. Otherwise, you will have to resort to the help of specialists.
It so happens that a woman calculated the day on which the long-awaited ovulation should begin, but she did not come. This means that there is some kind of malfunction in the body and an urgent need to consult a doctor. Let's take a closer look at this issue.
Every woman needs to know
When to expect this phenomenon
After the onset of ovulation, the mature egg leaves the follicle to fuse with the sperm. That, in turn, lives a maximum of 7 days, and usually no more than three. The life cycle of an egg is 12-24 hours. Therefore, it is necessary to calculate on what day of the menstrual cycle a woman has ovulation.
There are several main points:
- the menstrual cycle should be counted from the first day of the last month to the first day of the next period;
- the egg may not mature, if there is any failure 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 come, but menstruation will not come, in this case, you also need to contact a specialist.
If the right time is missing
You can meticulously calculate on what day ovulation will occur, when the cycle lasts 27-29 days, but it never comes. This is usually due to problems in the hypothalamic-pituitary-ovarian system. Dysfunction is caused by:
- genetic factor;
- inflamed genitals;
- stress.
Also, the cause may be an infectious disease that affected menstruation, or climate change when traveling on vacation. Research scientists have led to an unexpected conclusion. It turns out that it doesn't matter on what day ovulation comes, 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. They accumulate estrogen and transform the hormone androgen, which is responsible for the process. Thus, the lack of hormones leads to serious problems: the lack of menstruation. However, the same can happen if a woman is overweight.
Study of tests for genital 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 come. There is nothing terrible here, because this phenomenon occurs even in absolutely healthy women. The number of such anovulation cycles is increasing every year. For example, up to 30 years old, their number is 2-3 per year, and in 40 years - already 4-8.
In any case, you need to be sure to find out the cause of what happened. It is necessary to undergo an examination by an endocrinologist or gynecologist in order to receive advice or competent treatment. Most likely you will have to:
- undergo an ultrasound examination of the ovaries, pancreas and thyroid gland;
- to be tested for the presence of genital infections, the level of hormones;
- take blood and urine tests.
If ovulation has not been observed for more than a year, although sexual activity proceeds regularly, treatment is prescribed. Doctors usually prescribe the medicine Klostilbegit. 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.
It is not necessary to carry out the treatment yourself. Therapy should take place under the watchful supervision of a physician so that he can monitor the body's response. Otherwise, there is a risk of serious complications. Before prescribing a medication, a woman needs to undergo an examination and be sure to pass several tests:
- a blood test to test immunity in rubella;
- patency of the fallopian tubes;
- crops for the detection of gardnerella, mycoplasma, Trichomonas, ureaplasma, chlamydia, candida;
- smear for oncocytology;
- analysis for hepatitis C, B;
- analysis for HIV, syphilis.
During the appointment, the doctor tells the patient from which day of the menstrual cycle the process of ovulation stimulation should begin. Usually the drug is taken from 5 to 9 days of the cycle. If additional stimulation is carried out using Puregon, then from 3 to 7 days.
Therapy with these means should not be more than 6 courses in a row. Otherwise, ovarian depletion may develop, which is dangerous by early menopause. When treatment does not bring the desired result after the third course, the doctor usually reconsiders the methods of treatment.
Premature egg release
Sometimes ovulation is observed ahead of time. This happens for a number of reasons.
- Various pathologies.
- Strong physical activity.
- Climate change, lifestyle change or severe stress.
- Weight gain or loss.
- Medical treatment.
These factors are not always noticeable for a woman. She continues to live as before, but a hormonal imbalance begins in the body, which can affect the duration of the month, as a result of which the egg comes out earlier than expected.
Long-awaited pregnancy
This shift in your body will not affect your health in any way if you are not going to get pregnant and are not using the calendar method for contraception. However, early egg release can come as a surprise in several cases:
- IVF is prescribed, therefore, medications must be taken strictly after ovulation;
- you think that it is impossible to conceive a child after menstruation.
If you have a cycle of 33 or more days, it is very important to calculate on what day ovulation starts, so as not to miss such an important event. To do this, you need to closely monitor your health and body signals. Need to.
- Measure basal temperature regularly. It is best to measure it at the same time and write down the readings in a notebook.
- Track vaginal discharge.
- Conduct special tests that can detect a surge in luteinizing hormone.
- Conduct an ultrasound study to assess the growth of follicles (folliculometry).
- Take tests to track the level of hormones (FSH, LH, progesterone, estradiol).
Of course, when the cycle lasts 32 days, you can calculate at home on what day to wait for ovulation, and you can monitor the temperature and discharge at home. However, these methods are not very reliable. Tests and studies cost a lot of money and take time, but this will determine the best time to conceive a child.

When to do an ovulation test?
They are done 5-7 days before its expected start. This is with the condition of a regular menstrual cycle, since otherwise you need to buy more tests and use them about 10 days before the follicle rupture, that is, almost every day.
With a late onset of the luteal phase it is advisable to use the device on days 13-21 of the menstrual cycle. After receiving a positive result, the test is no longer needed, since it fulfilled its function.
Can the cycle be corrected / restored?
Medically easy to do, but it is important to understand why you need to interfere with the menstrual cycle.
If late ovulation variant of the norm, then there is no need to restore the cycle for the "average value", since the consequences will be unpredictable.
In cases of persistent hormonal imbalance(increase / decrease in prolactin, progesterone), serious diseases, it is imperative to correct and restore the menstrual cycle. For this, there are special drugs, inhibitors or hormone analogs, which normalize hormonal status.
For example, among gynecologists he uses popular medicine"Duphaston". It stimulates the onset of the luteal phase, and is also an analogue of progesterone.
Sometimes combined oral contraceptives are used... However, if a woman, then it is most reasonable. After 2 months, the cycle will recover on its own.
Is it possible to conceive, how does it affect pregnancy?
Late ovulation is not an obstacle for pregnancy and subsequent bearing of the fetus. However, it is permissible to say so only if it refers to a variant of the norm and is just a consequence of a long menstrual cycle.
Minor hormonal disruptions short-term nature also do not pose a danger to conception, but in the case of serious diseases and significant endocrine disorders, pregnancy is unlikely.
For instance, with increased prolactin or an insufficient amount of progesterone, fertilization is almost impossible, which indicates the need for medical attention. Each case is different.
Who is most likely to conceive?
Untimely follicle rupture does not affect gender in any way unborn child. Here it is impossible to calculate with accuracy and in advance, since such biological parameters depend to a greater extent on the partner. It is in a man that the Y chromosome has an X and Y program, in contrast to the egg.
Scientists have found some connection between the sex of the child and the woman's ovulation. For example, you need to have intercourse immediately before ovulation, and then, 2-3 days before its onset, stop sexual relations.
With the boy going on everything is exactly the opposite: it is advisable to start sexual intercourse precisely during ovulation.
Key factor here is the exact definition of the luteal phase of the cycle, which will indirectly help to influence the sex of the unborn child.
In conclusion, it must be said that late ovulation is not an independent diagnosis, but just a symptom, which can be a variant of a norm or pathology. With a long menstrual cycle, late rupture of the follicle is logical and logical. This does not in any way speak in favor of a serious illness.
If the doctor or patient has doubts or an alarming clinical picture, then it is necessary to carefully examine and check the hormonal status.
Only after the diagnostic results you can make final conclusions. In any case, it makes no sense to panic, since laboratory research data will answer all your questions.
When the ovulatory period begins, the body becomes completely ready to conceive a baby. Therefore, women who want to become pregnant begin to calculate ovulatory days in order to accurately determine the most favorable day for conception. If, with a standard 28-day cycle, the egg comes out in the middle of it, then what about girls with a smaller or larger cycle? If the cycle is 30 days, then when will there be ovulation, how to make error-free calculations and feel the onset of day X, if a woman, for example, has late ovulation?
Ovulation is a certain female state when a mature sex cell is released from the ovary, ready for fertilization. In fact, ovulation is the phase of the cycle that follows between the follicle-stimulating and luteinizing phases.
In most women, the maturation and release of the female cell is regular, systematic, repeating every 20-35 days. And follicular and gonadotropic hormonal substances regulate the frequency of ovulatory periods. At the very beginning of the female cycle, many cells are generated that develop in the follicular structures of the ovary. One of them is much ahead in the development of the rest, acquiring a dominant status.
The duration of development and maturation of the egg is about 11-15 days. By the time of the final maturation of the dominant follicle, it ruptures and the cell comes out. All of these processes are controlled by the estrogen hormone. But when the cell finally matures, the estrogen falls, and instead the level of progesterone rises sharply. It is this hormonal spike that causes the follicle to rupture when ovulation occurs. From this moment until the end of the cycle, progesterone is already responsible for all processes associated with the egg.
The ovulatory period lasts about 12-48 hours, which is due to the individual characteristics of the female body. When ovulation ends, the next phase of the cycle begins - luteinizing, when the onset of conception becomes impossible. There are many ways to calculate the ovulatory phase, some of them are more accurate than others, but each deserves attention.
How to calculate ovulation for a 30 day cycle
In some cases, additional examinations are required
When a woman cannot get pregnant for a long time, she involuntarily begins to calculate the favorable days of the cycle for a successful conception. In other words, it begins to calculate the ovulatory day. Experts recommend calculating ovulation using a simple formula. From the date of the expected start of the next menstruation, you need to subtract 14 days, since the duration of the luteinizing phase is normally exactly 2 weeks.
So, we are interested in when the ovulatory period begins, if the cycle is 30 days. From 30 (cycle duration) we subtract 14 (days of the second stage of the cycle). It turns out 16, which means that on day 16 ovulation should happen with a cycle of 30 days, but some discrepancy is allowed ± 2 days. It is on this principle that they count on what day the egg matures and leaves with other indicators.
If a woman's cycle length is unstable, then it will be problematic to calculate the onset of the ovulatory period in a calendar way. In such situations, you can use other methods of calculating the date of release of the female cell, which include ultrasound monitoring, testing with pharmacy strips and basal measurements.
Ultrasonic monitoring
This method for determining the ovulatory phase is also called phylliculometry. The purpose of this study is to monitor follicular growth and release of an egg from the ovary.
- With a 30-day cycle, ultrasound monitoring begins on the 10-11th day of the cycle, that is, approximately 4-5 days before the middle of the monthly cycle.
- Subsequent sessions of ultrasound control of the egg are carried out every two days and last until the release of the egg.
- The onset of the ovulatory period is confirmed by ultrasound diagnostics, when the day before the size of the follicle was 20-24 mm, and now the growth of the yellow gland has begun.
- The procedure can be performed through the vagina or through the abdominal wall.
- With an intravaginal examination, no preliminary preparation is required, the main thing is to empty the bladder.
- In an abdominal examination, a traditional examination is performed through the abdominal wall. In order for it to pass without difficulty, three days before monitoring, it is necessary to exclude all products that can provoke flatulence or bloating, and on the day of the examination, you must not eat and drink at least a liter of water.
Ultrasound monitoring requires certain financial costs, but it is the most accurate method for determining the date when ovulation occurs. There are also less expensive methods for determining the onset of ovulation.
Basal measurements
Measurements are taken in the morning, immediately after waking up
Correct measurement of basal temperature will help determine if the patient is normal, early or late ovulation. This is one of the easiest ways to determine auspicious days for conception. For its use, it is necessary to measure rectal temperature indicators daily for several months. This should be done after waking up in the morning, while you cannot get out of bed. I just woke up, and right behind the thermometer. All results must be scrupulously marked on a special chart. At the end of the cycle, all points with the measurement results are connected into a broken graph. Measurements are not taken during menstruation.
On days when the graph shows a sharp decrease, and then a rapid increase in temperature, ovulation occurs. It is better to use simple mercury thermometers for measurements, although electronic ones will do quite well. The main thing is to make all measurements with the same thermometer, then the results will be as accurate as possible. With the help of such a graph, a woman can easily determine fertile days, as well as the nature of egg maturation (early or late ovulation), etc.
Testing
An easier way to determine the ovulatory phase is the use of special pharmacy strip strips. Such tests are available at any pharmacy outlet. Since we are interested in ovulation with a cycle of 30 days, then from about the 13th day we need to start taking measurements. If ovulation is not observed, then the second strip will be absent. But on the eve or on the 15th day, the test line will be as bright as the control one. A similar sign says that the coming ovulatory period is coming, which must be expected in the next 24 hours.
Testing is carried out by analogy with tests for detecting conception. You need to lower the strip into a container with fresh urine for a few seconds, then put it on a dry surface and after about five minutes read the result. If the test strip appears, but the control strip is absent, then the testing is considered unreliable, since such a test is spoiled, it cannot show the correct, true result.
Signs of an egg release
A woman will be able to determine the onset of ovulation by internal sensations, external signs and various changes in the body. Not always the ovulatory period can reveal itself with pronounced manifestations, some women do not have any symptoms. But experts say that if you listen to your inner feelings, you can feel the time when the egg will leave the ovary.
First signs
The approaching onset of the ovulatory phase can be guessed by various symptoms.
If a girl has long reached puberty and reproductive age, and there are no signs of ovulation, then there is a possibility that anovulation is taking place. In addition, the absence of any ovulatory signs indicates the probable infertility of the patient. The main thing is to notice the problem in a timely manner and contact a specialist who will select the drugs necessary to correct the cycle.
Symptoms of the onset of the ovulatory period
As mentioned above, with the onset of the ovulatory period, changes occur with cervical mucus, which becomes more abundant and liquefies, acquiring the consistency of an egg white. It is with such secretions that the body tells a woman that she is ready to conceive. As for the basal temperature indicators, they fall before the immediate onset of ovulation, and the next day they rise sharply. It is after this increase that you need to wait for the release of the egg. Those couple of days when there will be a slight increase in temperature are considered the most fertile, it is then that the chances of conception are maximum.
Before the onset of the ovulatory phase, a serious hormonal change occurs, associated with an increase in the production of luteinizing hormone. By the way, tests for determining ovulation work on the principles of detecting this hormone, or rather, on its reaction with certain chemicals. Also, the onset of ovulation is indicated by some malaise, soreness in the abdomen and pulling discomfort in the lumbar region.
Also, signs such as increased libido, swelling of the mammary glands, sudden mood swings and excessive, chronic fatigue, tearfulness and tearfulness also speak of the onset of the ovulatory phase.
Early and late ovulation
Ovulatory periods are late or occur later than usual, i.e. early and late ovulation. If, with a 30-day cycle, the cell matures on days 11-12, then such ovulation is considered early, but if it began later than the due date, then the late ovulatory phase is diagnosed. Such shifts can occur against the background of frequent sexual intercourse, exhausting diet, heavy physical exertion, hormonal disorders, diseases, etc.
At the same time, the probability of conception remains depending on how many days ovulation lasts. In fact, this action takes only a few minutes while the cell ruptures the follicle and gets out of it. Everything, in fact, ovulation happened. But in medicine, it is customary to call the ovulatory period not only the time of release of the female cell, but also the period of its existence.
If the egg does not come out
In some cases, during the cycle, ovulation does not occur at all, then they talk about anovulation. Even in the healthiest patients, the cells are not able to mature at every cycle, about a couple of cycles remain without ovulation, which is quite normal. Gradually, these cycles become more and more, as the body ages, and follicular reserves are depleted. By the age of 35, almost every second or third cycle is anovulatory. In addition to physiological reasons, a variety of psycho-emotional experiences, stresses, inflammatory pathologies of the genital organs and the genitourinary system, dysfunctional disorders of the activity of intraorganic structures, etc., can also provoke such a state.
So, calculating the ovulatory period is not at all difficult, even on your own. If traditional home methods like basal charts or ovulatory pharmacy tests do not work, then you need to contact a specialist who, if necessary, will conduct ultrasound monitoring.
