The exact number of days after menstruation when it is easy to get pregnant varies from person to person, but it is generally easiest to get pregnant when you have sex during ovulation. A woman can ovulate at any time during ovulation and the egg cells will live in her body for 1-2 days after ovulation, so sex during this time is the easiest time to form a fertilized egg and get pregnant. Since the ovulation period varies depending on the menstrual cycle, the number of days after menstruation to get pregnant depends on each person’s menstrual cycle. For women with regular menstrual cycles, the day of ovulation is the 14th day before the next menstrual period. The day of ovulation plus the 5 days before and 4 days after the day of ovulation is called the ovulation period. In addition, some physical changes will occur during ovulation, such as stretched, clear and thin leucorrhea and an increase in body temperature of about 0.3℃. In addition, although it is easiest to get pregnant when you have sex during ovulation, it does not mean that you will never get pregnant during periods other than ovulation, and those who do not plan to have children should pay attention to contraception.
