A few days after the end of the period is the safe period

The safe menstruation period is generally calculated from the first day of menstruation. The 7 days before menstruation and the 8 days after menstruation are relatively safe, which is often referred to as "7 before and 8 after menstruation". But the safe menstruation period is not absolutely safe, it just means the chance of pregnancy is very low, and this safe menstruation period is relatively accurate for people with regular menstruation, if the menstruation is irregular, it is generally prohibited.

How many days after the menstrual period is the safe period?

Generally, the safe menstrual period is 7 days before menstruation and 8 days after menarche.

The safe menstrual period is divided into the safe menstrual period before ovulation and the safe menstrual period after ovulation. From the day after the end of the menstrual period 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. The safe menstrual period after ovulation is safer than the safe period before ovulation, but the safe menstrual period is not absolutely safe, because the female ovulation time is affected by environmental damage and mental fluctuations, the ovulation period can be delayed or advanced, and even additional ovulation period may occur.

Are the first seven days and the last eight days of menstruation the safe period?

The "first seven" refers to the seven days before menstruation, and the "last eight" refers to the eight days starting from the first day of menarche. It should be noted that "the last eight" does not refer to the eight days after the end of the menstrual period. For example, if a woman starts her period on September 20 and ends on September 26, then the "first seven" refers to the seven days starting from September 13, and the "last eight" refers to the eight days before September 27, that is, the period from September 13 to September 27 is the woman's safe menstruation period.

However, the "first seven and last eight" of the female safe period depends on the menstrual cycle. This method of calculating the safe menstrual period is generally suitable for women with a menstrual cycle of about 28 days and regular menstruation. If a woman's menstrual cycle is less than 26 days, generally speaking, the "first seven" can still be calculated as the safe menstrual period, but the "last eight" is not suitable. Contraception during the safe period can also be affected by factors such as the mentality, climate, and environment, which may cause early, delayed, or even additional ovulation. Therefore, contraception during the safe period is not absolutely safe.
