When is the safe period for girls?

When is the safe period? Except for the menstrual period and ovulation period, other times are safe periods. Women's safe period is divided into safe period before ovulation and 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 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 safe period.

How to calculate a woman’s safe period? 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 seven days before and eight days after the first day of menarche is the safe period, which is often called "seven before and eight after". The seven days before menstruation and eight days after menstruation are the safe period for adult women, which is a calculation method used by most people for contraceptive measures. In addition to using the calendar method to calculate the number of days, women's safe period can also be calculated according to ovulation temperature method and secretion observation.

However, the safe period of contraception is not absolutely safe. Sometimes women ovulate early or late, and the judgment of the safe period will become invalid.
