When is the safe period for girls?

When is the safe menstrual period for girls? 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.

When is the safe menstrual period for girls

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.

The safe menstrual period refers to the period from the end of the previous ovulation period to the next ovulation period. 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. Seven days before menstruation and eight days after menstruation are the safe menstrual period for adult women, which is a calculation method used by most people for contraceptive measures. In addition to the calendar method using the number of days to calculate, there is also the ovulation temperature method and secretion observation. However, 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.

How to calculate the safe menstrual period

Normal women of childbearing age have a menstrual period once a month. From the beginning of menarche to the first day of menarche of the next menarche, it is called a physiological cycle. For example, from the perspective of contraception, each menstrual cycle of a woman can be divided into menstrual period, ovulation period and safe menstrual period.

Women's ovulation period is generally about 14 days before the next menstrual period. After the egg is discharged from the ovary, it can survive in the fallopian tubes for 1-2 days, waiting for fertilization; the man's sperm can maintain fertilization ability for 2-3 days in the woman's reproductive system, so it is very easy to get pregnant by having sex a few days before and after the egg is discharged. To be on the safe side, we call the 5 days before and 4 days after ovulation, a total of 10 days within the ovulation period, the ovulation period. Since it is very easy to get pregnant during sexual intercourse during the ovulation period, the ovulation period is also called the fertile period or the dangerous period of pregnancy. Starting from the first day of a woman's next menarche, the last 14 days or minus 14 days is the ovulation period. The ovulation period plus the first 5 days and the last 4 days are called the ovulation period.

Women can self-test their safe period. For example, if a woman's menstrual cycle is 28 days, and the first day of her menarche is December 2, then the next menarche will be on December 30 (December 2 plus 28 days). Subtract 14 days from December 30, and December 16 is the ovulation period. The ovulation period, the 5 days before and the 4 days after, that is, December 11-20 is the ovulation period. Except for the menstrual period and ovulation period, the rest of the time is the safe menstrual period.
