Does ovulation happen before menstruation – this question torments a lot of women. Fertilization of the egg is possible only if ovulation occurs before the cycle. The best time for pregnancy is in the middle of the menstrual cycle. Ovulation before menstruation occurs, but very rarely, in such cases, two eggs mature, and a woman can give birth to twins. In this case, this may occur either due to the onset of repeated ovulation, or due to a failure of the cycle.
How long before the appearance of bloody discharge should ovulation occur
After a follicle has formed in the ovary, the inner lining of the uterus begins to increase. After that, the egg enters the fallopian tube, this moment comes about two weeks after menstruation, until the 16th day before it. These processes are extremely important for the intended fertilization of the egg.
After the egg enters the body of the uterus, spermatozoa also penetrate here, also through the fallopian tube, only on the other side. Only after the meeting of the egg with the sperm is fertilization performed. If this does not happen, the egg is excreted by the body outside, that is, menstruation occurs. It turns out that you can get pregnant a week before your period, although the chances are not so great. 5 days before their onset – even less.
Gynecologists believe that the optimal cycle of menstruation is 28 days, the time for conception is the middle of the cycle. At this point, everything is in place for a successful fusion of the egg with the sperm.
How long does the ovulation period last
Those women who plan to conceive, keep a calendar of ovulation dates. And this is correct: in order for conception to occur for sure, you need to know the period and duration. Based on the total duration of menstruation, the ovulatory period occurs:
- with a cycle of 21 days for 5-9 days;
- with 25 after 9-13 days;
- with 30 for 16-20 days;
- with 35 for 19-23 days.
Provided that the monthly regularity does not differ, then it is extremely difficult to correctly calculate the day of the onset of the ovulatory period. In this case, it is better to use other, more accurate methods of deduction. It lasts for each woman in different ways.
Answering the question whether there can be ovulation before the most monthly, we come to an unambiguous – in most cases it can not. It happened that women got pregnant before their periods – such cases are very rare.
Gynecology knows cases when women get pregnant on the day of the cycle, which is considered completely zero. This is explained by changes in the hormonal background, this happens against the background of emotional state, stress and other factors.
Due to severe stress, the menstrual cycle can shift, affecting the period of ovulation. As a result, two ovaries are able to secrete an egg. Not necessarily on the same day, it can happen on different days, and pregnancy will occur during menstruation.
Can it come sooner
In cases where a woman’s cycle is 35 days, even if she is absolutely healthy and her monthly periods come regularly, the release of a mature egg may occur earlier. And the fertile period-later for a week or a little longer.
This can provoke:
- Hormonal disorders in the body.
- Emotional overstrain and stress.
- Weakened immune system.
- Exacerbation of chronic diseases.
- Violation of metabolic processes Overeating or, conversely, starvation.
- Sudden climate change.
- Heavy physical activity
The fertile period may also shift due to the withdrawal of contraceptive drugs, after an abortion or due to a miscarriage.
Does the absence of ovulation before pregnancy mean conception
You can conceive a child only when a woman has matured an egg. The absence of ovulation indicates that this process does not occur in the body of the expectant mother. This means that there can be no question of any pregnancy. In such cases, you need to go to the gynecologist and find out the cause of what is happening. The root cause of this may be a hormonal imbalance.
You can correct it with a specially selected therapy. If the cause cannot be established, doctors resort to radical methods, for example, during the period of alleged ovulation, the patient is injected with a drug that causes the formation and maturation of the follicle with the further release of the egg.
Is it possible to fertilize an egg after ovulation
No, a miracle, in this case, will not happen. A day after ovulation, women have a period that gynecologists call absolute infertility. For those who do not know the answer to the question of whether there can be ovulation before menstruation, we explain the essence of what is happening during the ovulatory period.
Ovulation divides the monthly cycle into two parts. The first is the phase of follicle maturation (duration, on average, 6-9 days). The second is the yellow body phase, the duration of this period lasts, depending on the cycle, and is, on average, 14 days. The second refers to the period of absolute infertility.
Pregnancy does not occur because a mature and ready-to-fertilize egg lives only 24 hours. Sometimes it can live even less. After it begins to collapse.
Can the ovulatory period occur before menstruation
The moment when the egg enters the uterus depends on the hormonal level and the duration of the follicular phase. In some young girls, these processes are very slow. Ovulation and pregnancy before menstruation are possible, due to the fact that the first phase becomes a little longer than usual. The primary cause of this may be a deficiency of the hormone estradiol. The moment of ovulation in such cases falls on the day of the beginning of menstruation, and the cycle itself should move.
Menstruation can not begin at the time of rupture of the follicle, because here comes the luteal phase, which lasts 14 days plus / minus 2 days.
If the ovulation period occurred at the beginning of the cycle and at this point the couple had unprotected contact, then the probability of fertilization remains high. In women in such cases, it is believed that ovulation occurred just before menstruation. In fact, the cycle, or rather its duration, has increased due to the follicular phase.
Probability of fertilization a week before the cycle
If pregnancy is not included in the family plans, then you need to be protected before the cycle constantly, even for a week. Although ovulation can not occur a week before menstruation, there is a chance of fertilization. This applies to young girls and women on the verge of menopause. In medical practice, such cases have happened. The reason for this may be too long periods, irregular cycles or severe stress loads.
The calendar schedule of pregnancy protection in such cases does not work, the probability of unwanted fertilization increases. In cases where the release of a mature egg fell on the period a week before the cycle, the woman must necessarily feel the characteristic symptoms of the fertile phase.
Is there a chance of pregnancy a day or two before the cycle
Many women believe that this is impossible. This statement is false, in fact, there is such a probability, although it is scanty. If a woman is absolutely healthy, then the greatest chances of pregnancy, namely 95%, fall in the middle of the cycle, the chance of fertilization of the egg a day before menstruation is reduced to 1 %, but it still exists. Gynecologists believe that unwanted pregnancies in women occur due to the fact that they simply incorrectly calculate the ovulatory period or because of a violation of the cycle itself.
Can ovulation be more than once
In almost all healthy women, ovulation occurs repeatedly during their lifetime. The regularity of the cycle does not play any role here. The approximate time of the second one is 24 hours or 2/3 days after the first one. The maximum difference is 1/1. 5 weeks in the same cycle. This fact is explained by the fact that both ovaries simultaneously matured eggs. At the time of release, the second hormone level decreases, but the probability of fertilization remains.
In conclusion: ovulation before menstruation
Summing up all the above, it can be noted that even the healthiest representative of the fair sex can have shifts in the ovulatory phase – this is the answer to the main question, which was mentioned above, whether there can be ovulation a week before menstruation, a day or just before them.
Such deviations are temporary, most often the regularity of the cycle is restored by itself. If this is a consequence of pathological changes in the body, then you can not do without the help of doctors.
