How many days after menstruation is the safe period?

Menstruation is a normal physiological phenomenon of women. Women will have menstruation when they ovulate. Therefore, there is a certain dangerous period before and after the menstrual period, which is the ovulation period. This time can easily lead to unexpected pregnancy. The period before and after the menstrual period is the safe period. So how many days after the menstrual period is the safe period? Let's ask the experts to introduce this issue.

Generally speaking, the safe period is seven days before and eight days after menstruation, that is, seven days before and eight days after menstruation. However, the failure rate of this algorithm is very high, because many women's menstrual cycles are unstable, and many times, factors such as emotions and stress will also affect women's endocrine system and cause abnormal menstrual periods.

From the perspective of contraception, each menstrual cycle of a woman can be divided into the menstrual period, ovulation period and safe period. Generally speaking, the ovaries of women of normal childbearing age release only one egg per month. The egg can survive 1 to 2 days after being released, and the sperm can survive 2 to 3 days in the female reproductive tract. The fertilization ability is mostly within 24 hours after ovulation. After 2 to 3 days, the sperm loses the ability to combine with the egg. Therefore, if you have sexual intercourse 2 to 3 days before ovulation and 1 to 2 days after ovulation, you may get pregnant. This period is called the fertile period or the dangerous period.

A woman's ovulation date 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, together with the ovulation day, a total of 10 days, the ovulation period. The rest of the time except the menstrual period is called the safe period. The safe period is divided into the safe period before ovulation and the safe 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 the end of ovulation to the day before the next menstrual cramps is the safe period after ovulation. The safe period after ovulation is safer than the safe period before ovulation.

The above is the issue that the experts introduced to us. The safe period for women is the view introduced to us by the experts above. By calculating the safe period according to the above method, we can accurately calculate the safe period and dangerous period for women. However, in order to avoid unwanted pregnancy, we should try to use condoms.
