The first 8 days of menstruation are the dangerous period

As we all know, the safe menstruation period is generally the seven days before and eight days after a woman's menstruation, that is, seven before and eight after. However, this does not mean that it is not easy to get pregnant. Therefore, the eighth day of menstruation is not a dangerous period of pregnancy.

Except for the menstrual period and ovulation period, the rest of the time is the safe period for women. Generally speaking, if a woman has a normal menstrual cycle of 28 days, the period from seven days before the first day of menarche to eight days after the first day of menarche is the safe menstrual period. For women with irregular menstrual cycles, this method is not advisable.

Women's safe menstrual period is mainly calculated based on the ovulation period and menstrual cycle. In addition to the calendar method, you can also calculate the safe menstrual period by measuring your body temperature during ovulation and observing your secretions. Combining the above three methods to calculate the safe period can improve accuracy. It should be noted that the safe menstruation period is not absolutely safe. Sometimes women ovulate earlier or later, so the judgment of the safe menstruation period will become invalid.

When is the safe menstrual period? Except for the menstrual period and ovulation period, the rest of the time is the safe menstrual period. Women's safe period is divided into safe menstruation period before ovulation and safe menstruation period after ovulation. The period from the end of menstruation to the day before ovulation is the safe period before ovulation. From the first day after ovulation to the day before the next menstrual period is the safe period after ovulation.

A woman's ovulation period is generally about 14 days before the next menstrual period. To be on the safe side, we call the 5 days before and 4 days after ovulation the total of 10 days in the ovulation period. Generally speaking, the ovaries of women of normal childbearing age only release one egg cell per month. The egg cell can survive for 1-2 days after being released, and the sperm can survive in the female reproductive system for 2-3 days. The fertilization ability is mostly within 24 hours after ovulation. After 2-3 days, the sperm will lose the ability to fuse with the egg cell. Therefore, if you have sexual intercourse 2-3 days before ovulation and 1-2 days after ovulation, you may become pregnant. This stage is called the fertile period or the dangerous period of pregnancy.
