How many days before menstruation is the safe period?

A woman's menstrual cycle is about 30 days. It is normal for it to be delayed or advanced occasionally. The safe period is also calculated based on the menstrual cycle. Generally, the 7-8 days before the menstrual period is the safe period, and the 7-8 days after the menstrual period is also the safe period. In addition, there is the ovulation period. Learn more about the safe period before the menstrual period.

1. The seven days before menstruation and the eight days after menstruation are the safe period for adult women.

1. The safe period is a method of calculating contraception. Compared with other contraceptive methods such as birth control pills, calculating the safe period has fewer side effects and is therefore chosen by most people. Generally, the seven days before menstruation and eight days after menstruation are the safe period for adult women. The current term is 3 days before and 4 days after menstruation. Generally, for women who have always had regular menstrual cycles, ovulation may occur on the 14th day before the next menstrual period. After the egg is released, it can survive for about 2 to 5 days, and the sperm can survive for 1 to 3 days after entering the female reproductive tract. Therefore, it is easy to get pregnant by having sexual intercourse 5-7 days before ovulation and 4-6 days after ovulation. Other dates are relatively safe.

2. 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.

3. In addition to the calendar method that uses days to calculate, there are also methods for calculating the safe period such as the basal body temperature method and the secretion observation method. It is worth noting that the safe period is not absolutely safe. Sometimes women ovulate earlier or later, and the judgment of the safe period becomes invalid at this time. Determining the safe period can only reduce the chance of pregnancy.

2. Is it safe period just after menstruation?

Generally speaking, the seven days before menstruation and eight days after menstruation are the safe period for adult women. The current term is 3 days before and 4 days after menstruation. Generally, for women who have always had regular menstrual cycles, ovulation may occur on the 14th day before the next menstrual period. After the egg is released, it can survive for about 2 to 5 days, and the sperm can survive for 1 to 3 days after entering the female reproductive tract. Therefore, it is easy to get pregnant by having sexual intercourse 5-7 days before ovulation and 4-6 days after ovulation. Other dates are relatively safe. Although theoretically the period just after menstruation is a safe period, because the first few days after menstruation are the safe period before ovulation, it is affected by many factors, which reduces its safety.
