How many days is normal for menstruation?

Girls will eventually have their periods. The first menstrual period is called the first menstruation. The age of menarche is mostly between 13 and 15 years old, but it may be as early as 11 to 12 years old, or as late as 17 to 18 years old. How many days does a girl’s period usually last? Let’s take a look at some common questions about periods. How many days of menstruation are considered normal?

The first day of bleeding (i.e. menstruation) is called the beginning of the menstrual cycle, and the time interval between the first days of two menstrual periods is called a menstrual cycle, which is generally 28 to 30 days, which is similar to the time of a lunar month. The length of the cycle varies from person to person. Occasionally, it can be early or late by no more than 7 days and can still be considered normal. That is, the menstrual cycle cannot be less than 21 days and cannot exceed 35 days. Menstruation will stop during pregnancy and lactation.

How many days does a woman's menstrual period usually last? The menstrual period refers to the duration of menstruation. Normal menstruation lasts 2 to 7 days, usually 4 to 5 days. Menstrual volume refers to the blood discharged during the menstrual period. It is difficult to make statistical analysis on the amount of menstrual flow. In clinical medicine, it is common to roughly estimate the amount by changing menstrual pads several times a day. Many people have measured that the average amount of menstrual blood is about 10 to 58 ml, and some women's menstrual blood volume can exceed 100 ml. Many people believe that excessive blood loss of more than 800 mg/month is a pathological condition. Generally, the heaviest bleeding occurs on the 2nd to 3rd day of the menstrual period. Due to differences in one's physical condition, age, climate, region and living conditions, the amount of menstruation sometimes fluctuates slightly, which is all normal physiological aspects.

Menstrual blood color refers to the color of menstrual blood. Menstrual blood is generally dark red, and is lighter in color at first, then gradually becomes heavier, and finally turns dark red and clear. In addition to blood, there are also fragments of uterine wall, cervical mucus and squamous epithelial cells in the vagina. The main characteristic of menstrual blood is not coagulation, but under normal circumstances, there are sometimes small clots.

Menstrual quality refers to the properties of menstrual blood. Under normal circumstances, the menstrual quality is neither thin nor thick, is not easy to coagulate, has no obvious blood clots, and has no special smell. Pathological changes in menstrual content are not only common menstrual symptoms, but also an important part of clinical medical dialectics. By understanding the changes in meridians, important diagnostic data can be provided for clinical medicine. When women have their first menstruation, the menstrual discharge is thick or sticky, which is called "thick menstrual discharge".
