How many days of menstruation is considered safe?

The four words "seven before and eight after" are not unfamiliar to young people, because they all know that this is the safe period. If they have sex during this period, most of the time they will not take contraceptive measures. However, some experts said that this statement came entirely from the public and was not scientifically convincing. Is this really the case? If so, how many days after a woman's menstruation is the safe period?

How many days after menstruation is the safe period

How many days after menstruation is the safe period? How many days after menstruation is the safe period? Generally speaking, the safe period for women is calculated according to the normal menstrual cycle, and the safe period is within 8 days after the menstruation ends.

The number of days after menstruation that are considered safe can be calculated using the calendar method, the basal body temperature method, and the secretion observation method. Of course, 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.

Is the first seven and the last eight a safe period?

Are the seven days before and eight days after menstruation the safe period? The seven days before and eight days after menstruation is a method used to calculate the safe period. The "seven days before" refers to the seven days before menstruation, and the "eight days after" refers to the eight days starting from the first day of menstruation. It should be noted that "the last eight" does not refer to the eight days after the end of menstruation. If a woman starts menstruating on September 20 and ends on September 26, then the "first seven" refers to the seven days starting on 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 period.

However, the "seven before and eight after" of a woman's safe period should be determined according to the menstrual cycle. This method of calculating the safe 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 a safe period, but the "last eight" does not apply. Contraception during the safe period can also be affected by factors such as mood, climate, and environment, which may result in early ovulation, delayed ovulation, or even extra ovulation. Therefore, contraception during the safe period is not absolutely safe.
