Women's physiological safe period calculator

The calculation method of women's physiological safe period is a practical tool for calculating women's safe period. A woman's ovulation period is generally about 14 days before the next menstrual period. Starting from the first day of the next menarche, the last 14 days or minus 14 days is the ovulation period. The ovulation period plus the first 5 days and the last 4 days are called the ovulation period. Except for the menstrual period and ovulation period, the rest of the time is the safe menstrual period. The safe menstrual period is not necessarily "safe". It is recommended that contraceptive drugs or special contraceptive tools should be used as much as possible during sexual intercourse during the safe menstrual period.

Generally speaking, women only ovulate once in a menstrual cycle, and the egg cells have a certain survival time. The safe menstrual period bypasses this period, so it is relatively safe. However, early or delayed ovulation may occur, and even two eggs may be ovulated in one menstrual cycle, which is very likely to lead to unwanted pregnancy.

The safe menstrual period refers to a woman's menstrual cycle, which is related to the menstrual period. The female menstrual cycle is normal between 26 and 35 days, with a difference of about 10 days. This shows that the safe period of menstruation is not necessarily as safe as expected. In Hong Kong, China, the safe menstrual period is generally considered to be the 7 days before and 7 days after the menstrual period, so it is also known as the first seven and the last seven.

Normal women of childbearing age have menstruation every 26 to 30 days. Women's menstrual cycle is divided into menstrual period, ovulation period and safe menstruation period. The so-called safe menstruation period is the period when it is not easy to get pregnant, and the ovulation period is the period when it is easy to get pregnant. For adult women, it is very important to understand the ovulation period and safe menstruation period.

Medically proven, the uterine wall repair period is within 4 days after menstruation. At this time, the natural environment of the uterine wall is not suitable for pregnancy. This stage is generally called the safe menstrual period. Women cannot get pregnant more than 24 hours after ovulation, but this time range is not uniform, which leads to unexpected pregnancy. The few days before ovulation and during ovulation are the easiest to get pregnant, which is called the safe period of pregnancy. From the first day of menstruation to the safe period of pregnancy is the safe menstruation period.

With the improvement of the uterine wall, that is, from 4 days to 14 days after menstruation, during this period, the uterus is in the best natural environment, it is best to get pregnant, and of course it is also the best time for ovulation, so it is easy to get pregnant successfully.

After 15 days after menstruation, the uterine wall begins to weaken, and this is not the best environment for pregnancy. At this time, it is also relatively safe, also known as the safe menstruation period. After the 24th day, it sheds again and enters a new menstrual cycle.

Simply put, if you want to get pregnant, you need to actively have sex during the ovulation period, so that you can get pregnant. Friends who don't want to get pregnant but want to have sex can have sex during the woman's safe period and enjoy a world for two.

Safe period calculation method

The female safety period is closely related to the female menstrual cycle. If the menstrual cycle is relatively regular, generally the 7 days before menstruation and 8 days after menstruation belong to the menstrual safety period. However, the menstrual safety period is not absolutely safe, it just has a low chance of pregnancy.

Because the time of female ovulation is affected by factors such as the external environment, climate, one's own mood and physical and mental health, ovulation may be delayed or advanced. Therefore, the safe menstrual period is not absolutely safe.
