How many days does a woman's menstruation last?

Women have menstruation every month, and menstruation is divided into several stages, such as the first time a woman has menstruation, which is called menarche. Many women are confused when they get their first period, because most women don’t know how many days of menstruation are normal when they get their first period. In fact, menstruation dates are regular, occurring every month, and the time difference is not too big.

The average age of menarche for girls is 12 years old, but it is normal to have menarche between the ages of 8 and 16. Many factors, including genetics, diet, and physical health, can cause menarche to come earlier or later. The cessation of menstruation marks that a woman has entered menopause, also known as menopause. The average age of menopausal women is 51 years old. Of course, just like menarche, many factors such as genetics, disease, surgery and medical treatment can advance or delay menopause. It is normal to enter menopause between the ages of 40 and 58. Menopause occurring before the age of 35 is defined as premature aging.

The length of the menstrual cycle varies from person to person. Every woman's menstrual cycle is long or short. It is normal for a woman's longest cycle minus the shortest cycle to be within 8 days. It is very rare for women to have a period that differs by less than 4 days. The difference in length between 8 and 20 days is somewhat abnormal. For women, a difference of more than 21 days in length is considered a serious abnormality.

The menstrual cycle is counted from the first day of menstruation because the onset of menstruation is quite consistent with the cycle of hormone secretion. Menstruation can generally be divided into several stages as shown in the table below. The length of each stage varies from person to person and depends on the cycle.

In fact, questions like how many days a woman's menstrual period lasts can be discovered by just observing her a few times. Because menstruation usually lasts about a week, the time of each menstruation is close to the time of the first menstruation. People can also infer the time of menstruation through certain changes in the body. Of course, women should keep warm during menstruation.
