How to calculate the days to the next menstrual period

For women with regular menstrual cycles, the number of days between the first day of this menstruation and the first day of the next menstruation is the menstrual cycle. For example, if this menstruation is on January 1, and the first day of the next menstruation is January 31, the 30 days in between are the menstrual cycle. If the current menstrual period is on January 1, the next menstrual period will be on January 25, and the 24 days in between are the menstrual cycle. Most women have a menstrual cycle of 28-30 days, but not all women have a regular cycle. Even if the menstrual cycle is not 28-30 days, as long as it is within the normal range, it is fine.

The normal range for a menstrual cycle is 21-35 days, and the normal range for a menstrual period is 2-7 days. If a woman has an irregular menstrual cycle, she can use a record method to record the first day of her period and the time of her period each time, and decide whether she needs to regulate her menstruation based on the exact time recorded and the results of estrogen level tests.

The menstrual cycle, that is, the number of days of menstruation, is calculated based on the time interval from the first day of this menstruation to the first day of the next menstruation. Each menstrual cycle starts from the first day of menstruation. Everyone's menstrual cycle is different. Normally it should be 21-35 days, with an average of 28 days. There are also some women whose menstrual cycle is 40 days or longer, but as long as the menstruation comes on time, the menstrual cycle is regular, which belongs to her own cycle. If your menstrual cycle is less than 21 days, you should see a doctor for menstruation regulation.

Menstruation is the shedding of the uterine wall and bleeding that occurs during the ovarian cycle. Normal menstruation is regular and self-limited. The first day of bleeding is the beginning of the menstrual cycle, and the time interval between the first days of two menstruations is called a menstrual cycle. For example, January 1st is the first menstrual period. The next menstrual period should be around January 1st. It is basically normal to have a period 7 days earlier or 7 days later. The ovulation period is also calculated before the next menarche. Those who do not have pregnancy requirements can choose safe period contraception to avoid accidental pregnancy. Those who want to get pregnant can choose to have sex during the ovulation period to increase the probability of pregnancy.
