How many days is a normal menstrual period

Menstruation is something women experience every month, and it is also a way for the body to excrete toxins. Many factors may cause irregular menstruation, and diet and lifestyle during menstruation should all be taken seriously. So, how many days is a normal menstrual cycle? What is the menstrual cycle like?

How many days is a normal menstrual cycle?

The measurement of the menstrual cycle starts from the first day of the current menstruation and ends on the first day of the next menstrual period, which is called the menstrual cycle. The calculation of the menstrual cycle should include the time of menarche. For example, the first day of your most recent menstruation was September 31st, and the first day of your previous menstruation was September 1st. The number obtained by subtracting the two dates is 30, which means that the menstrual cycle is 30 days.

Under normal circumstances, women's menstrual cycle is 28 to 32 days. Due to individual differences, the length of the menstrual cycle can vary from person to person. A week earlier or later can be considered normal. As long as a certain periodicity can be maintained, it cannot be considered as irregular menstruation.

Also, when many women visit the gynecology department, they are usually asked by the doctor about the due date of pregnancy. The due date of pregnancy refers to the time of the menstrual period closest to the date of consultation, which needs to be calculated from the first day of bleeding.

In addition, when a young girl has her first menstruation, because the uterus and ovaries are in the development stage and their functions are not yet complete, neurological disorders and irregularities will occur, causing abnormal menstrual cycles. Perimenopausal women will also have abnormal menstrual cycles because the ovaries gradually decline, causing disorders in growth hormone metabolism. Both of these conditions are normal and there is no need to worry.
