How many days does a woman's menstrual period usually last?

Menstruation is something that every woman will experience. It is a normal physiological phenomenon. However, many female friends do not have much knowledge about menstruation, and do not know whether their menstruation is normal.

In medicine, the first day of menstrual bleeding is generally counted as the beginning of the menstrual cycle, and the menstrual period is generally 3-7 days. The interval between the first days of two menstrual periods is one menstrual cycle. A shortening or extension of about 7 days is still considered a normal menstrual cycle. A normal, stable menstrual cycle is 28-30 days. However, due to the influence of race, genetics, and internal and external environment, there are individual differences, generally ranging from 21 to 35 days. In addition, some people may have their period a week earlier or later due to internal and external environmental factors, which is all normal. For girls who have just reached menarche, irregular menstrual cycles are a normal physiological phenomenon and will generally return to normal within a year.
