How often does my period come?

Menstruation is a normal physiological phenomenon and is of great significance to women's lives. The scientific name of menstruation is menstruation, which is a substance produced by the female uterus and needs to be discharged from the body through the vagina regularly. Because the health of the female reproductive system is closely related to menstruation, most women attach great importance to menstruation. How often is it better for menstruation to come? Let’s take a look at the explanation below.

Menstruation is regular, cyclical uterine bleeding. Strictly speaking, along with this bleeding, there should be maturation of follicles, ovulation and formation of corpus luteum in the ovaries, and changes in the endometrium from proliferation to secretion. However, in clinical practice, uterine bleeding without ovulation is common, which is called anovulatory menstruation.

The first menstrual period is called menarche, which usually occurs between the ages of 13 and 15, but may occur as early as 11 to 12 years old or as late as 17 to 18 years old. The age of menarche in different regions of my country is not much different, but those who are weak or malnourished may have a later menarche, while those who are strong and well-nourished may have an earlier menarche.

The first day of bleeding is called the beginning of the menstrual cycle, and the interval between the first days of two menstrual periods is called a menstrual cycle, which is generally 28 to 30 days. About 7 days earlier or later is still within the normal range, and the length of the cycle varies from person to person.

Normal menstruation lasts for 2 to 7 days, with an average of about 5 days. The amount of menstrual flow is difficult to calculate, and clinically, the amount is roughly estimated by the number of times menstrual pads are changed daily. Some people have measured that the normal menstrual blood volume is about 10 to 58 ml, and some women's menstrual volume can exceed 100 ml. Some people believe that monthly blood loss of more than 80 ml is a pathological condition. Generally, the heaviest bleeding occurs on the 2nd to 3rd day of menstruation.

Menstrual blood is generally dark red and contains, in addition to blood, endometrial fragments, cervical mucus and vaginal epithelial cells. The main characteristic of menstrual blood is that it does not coagulate, but under normal circumstances there are occasionally some small clots.

There are usually no special symptoms during menstruation. Some women may have a feeling of heaviness in the lower abdomen and lumbosacral area, some may have bladder irritation symptoms such as frequent urination, mild symptoms of nervous system instability such as headache, insomnia, mental depression, irritability, gastrointestinal dysfunction such as nausea, vomiting, constipation or diarrhea, and nasal mucosal bleeding.
