When the woman does not menstruate, does she have a fertile period?

Hi, my period is deregulated and I do not take the pill. I can not remember the last time I came, if it was in December or January ... When the woman does not menstruate has a fertile period or not?
Expert answer:

It depends. If the woman does not menstruate and this delay of menstruation is due to menstrual irregularity, she has a fertile period in it, because she continues to ovulate, which seems to be her case.

On the other hand, absence of menstruation It may also indicate that the woman is not producing eggs and, in this case, she has no fertile period. This can happen in cases of pregnancy, uninterrupted use of contraceptive pill, hormonal changes, among other causes.

O menstrual cycle has a duration that varies between 24 and 35 days. To know what your fertile period is, you have to count the days between one menstruation and another.

If, for example, the interval is 30 days, O 15th day will be your most fertile day, as you will probably be ovulating on that day.

However, the fertile period begins 3 days before and continues until 3 days later of the 15th day, because the spermatozoon can survive for up to 5 days inside your body.

Thus, for a cycle of 30 days, the fertile period will be 12th to 18th day of this menstrual cycle.

THE menstrual irregularity is common in the first 2 years after first menstruation. There are cases of teenagers in which the time between one menstruation and another is more than 40 days.

Otherwise, menstruation delays exceeding 35 days should be evaluated by a gynecologist, as they may be a sign of diseases such as polycystic ovary syndrome, uterine fibroids, endometriosis, hypothyroidism, among others.
