The safe period is related to the longest cycle, the shortest cycle, and the start of menstruation for each person. The safe period is not absolutely safe, and sometimes a woman's ovulation will be earlier or later, and the judgment of the safe period will become invalid. Judging the safe period only reduces the chance of pregnancy and cannot be used as a contraceptive method.
3 days before the ovulation day and 5 days after the ovulation day, it is easy to get pregnant! Other dates are relatively safe.
It's better to use some measures, otherwise it will be the woman herself who will be hurt at that time.

Usually the safe period is the first seven and the last eight, the problem is that these calculation methods are not absolutely safe, it depends on whether the woman's period is stable.

It depends on the menstrual cycle, how many days are the longest, how many days are the shortest, and how many days the menstrual period is, in order to get the safe period. But to understand that the so-called safety can only be said to be relatively safe, there is no foolproof safety, and it is recommended to do contraception. A woman's ovulation date is generally about 14 days before her next menstrual period.
Counting from the first day of the next menstrual period, the 14 days backward or subtracting 14 days is the ovulation day, and the ovulation day and the first 5 days and the next 4 days together are called ovulation.

Contraception during the rhythm period.
A few days before and after is a safe period.
Females of normal childbearing age.
Menstruation occurs once every 28 days or so, and from the perspective of contraception, it is possible to divide each menstrual cycle into menstrual periods.
Generally, the 8 days before and after your period are safe periods.
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 day before the start 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.
The post-ovulation safe period is safer than the pre-ovulation safe period. This is because some women sometimes ovulate earlier due to environmental changes and mood swings, so that the safe period before ovulation is shortened.
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. In addition to the calendar method, which uses the number of days calculation, there is also the basal body temperature method and the secretion observation method. However, the safe period is not absolutely safe, and sometimes a woman's ovulation will be earlier or later, and the judgment of the safe period will become invalid.
Contraception during the rhythm period is not safe. Inference algorithms are often unreliable. The time of ovulation is affected by the external environment, climate, emotions and health.
Factors such as state can lead to delayed or early ovulation, and there is also the possibility of additional ovulation. The failure rate of contraception during the safe period is about 20%, and people with abnormal menstrual cycles are not suitable for the contraceptive method of the safe period.
