How many days before menstruation is the dangerous period?

For women with regular menstruation cycles of about 28 days, eight days after menstruation and seven days before menstruation are safe periods. There are two types of safe periods: one is the safe period before ovulation, and the other is the safe period after ovulation.

What are the dangerous periods?

Since there is a safe period, the opposite is the dangerous period. In fact, the dangerous period is what we call the ovulation day. If a woman's menstruation is regular, then the ovulation day is two weeks before the next menstruation, that is, the first fourteen days. To be on the safe side, we usually call the five days before ovulation and the four days after ovulation, these ten days, collectively referred to as the ovulation period. During the ovulation period, it is very easy for women to get pregnant, so if you want to have a baby, you can have sex during these days, and the chance of success is very high.

How many days after menstruation is the safe period

The safe period after ovulation is from the first day after the end of ovulation to the day before the next menstrual cramps.

But in general, the safe period is not absolutely safe. It can only be said that the probability is small. Because many women with irregular menstrual cycles also have irregular ovulation, so there is still a chance of pregnancy.
