What is the danger period

summary

A woman's month is divided into three periods, which are safety period, menstrual period and danger period. But many people don't know when the danger period is. Let's introduce how to calculate the danger period.

What is the danger period

First of all, "safe period" and "dangerous period" refer to the time interval during the menstrual cycle when an egg meets sperm and becomes a fertilized egg, which is called "dangerous period", otherwise it becomes "safe period".

Secondly, because the egg may be fertilized in two or three days after discharge, sperm can survive after discharge, and can enter the egg in three or four days. Therefore, if the ovulation day (usually 14 days before menstruation) is taken as the base, the first four days and the last five days are the danger period, and the rest is the safety period.

Finally, if you don't want to be pregnant, you can choose to have rooming in the dangerous period, but it's not absolutely safe, just the probability of pregnancy is relatively low.
