How to calculate the menstrual cycle of girls

"Aunt Flo" is an affectionate name for menstruation among women, because it is a relatively regular physiological phenomenon for women, occurring almost every month and causing a certain impact on women's lives, but it is also a healthy phenomenon and does no harm to women's bodies. It is important for women to accurately calculate the menstrual cycle for pregnancy and maintaining physical health. Let’s take a look at how to calculate the menstrual cycle for girls.

1. How to calculate the menstrual cycle

Under normal circumstances, the menstrual cycle is 28 to 35 days. The length of the menstrual cycle varies from person to person. 7 to 10 days early or late can be considered within the normal range. As long as a certain regularity can be maintained, it cannot be considered as irregular menstruation.

2. Calculate the time of menstruation

A complete menstrual cycle starts from the first day of menstruation and ends on the first day of the next menstruation. Generally, this cycle is calculated as one month, but in fact it varies from person to person.

The first day of bleeding is the beginning of the menstrual cycle, and the interval between the first days of two menstruations is called the menstrual cycle. Therefore, the calculation of the menstrual cycle should include the time of menstruation.

Some women only count the time when their menstruation ends, so they may think that their menstrual cycle is shortened. Clinically, some women often complain of irregular menstruation, with two periods in a month. In fact, if you calculate carefully, it is normal to have a menstrual period once at the beginning and end of the month.
