Traditionally, seven days before menstruation and eight days after menstruation are safe periods for adult women, and are a calculation method used by most people for contraception.
Women of normal childbearing age have a menstrual period every 28 days or so, and the period from the beginning of this menstrual period to the first day of the next menstrual period is called a menstrual cycle. For example, in terms of contraception, each menstrual cycle of a woman can be divided into menstrual periods, ovulation and safe periods. Ovulation contraception is a method of contraception that stops sexual activity during ovulation.
This is a traditional method of contraception, which was one of the commonly used contraceptive methods at home and abroad before the advent of birth control pills and intrauterine devices.
The safe period is further divided into the pre-ovulation safe period and the post-ovulation safe period. The period from the day of menstruation to the first three days of ovulation is the safe period before ovulation. The safe period after ovulation is from the first day after ovulation ends to the day before the next menstrual period.
In general, the post-ovulation safe period is safer than the pre-ovulation safe period. This is because some women sometimes ovulate early due to environmental changes and mood swings, so that the pre-ovulation safe period will be shortened, and they do not know it, so the pre-ovulation safe period is not very safe. The chances of the ovaries releasing two eggs in a menstrual cycle are very rare, as detailed in this article.

Hello, now people generally think that it is more accurate to calculate the safety period, which is the so-called "first seven and last eight".
Among them, the "first seven" refers to the seven days before menstruation, which is a relatively safe post-safe period, which basically no one will understand. "Last eight" refers to the eight days after the first day of menstruation, not after the end of menstruation.
Because of the influence of emotional, climate, environmental and other factors, rhythmic contraception may cause early, postponed or even additional ovulation, so it is not so absolutely safe to use rhythmic contraception, so it is not recommended for the majority of women to use rhythmic contraception alone. The safe period is only relatively safe, not absolutely safe!

Normally, the first seven and last eight days of menstruation are safe periods. However, because some women have irregular menstrual periods, it is very unsafe to use contraception during the rhythm period. Some women only have 20 days of menstruation, so the "last eight" is obviously inappropriate.
Some women have menstruation for more than 30 days, so the "first seven" is not necessarily suitable.
Contraception during the rhythm period is very unsafe.

It's the safe period.
The safe period is seven days before menstruation and eight days after menstruation.
These fifteen days are safe periods.
Menstruation can be dangerous.
So make sure to make sure if your period is over or not coming.
The so-called safe period is 14 days before the day of your period, for example, if you come on the 30th, then push forward 14 days from the 30th, that is, the first few days before the 16th is your safe period.

About one-third of a person's life is spent in sleep, which seems to be a fundamental element of biology, but scientists still don't know it. According to the British magazine New Scientist, scientists have come up with several theories about the cause of sleep, ranging from simple theories to complex theories involving memory processing, but none of them have been confirmed. Sleep is made up of two completely different states: >>>More
