At what age do girls usually start menstruating?

The first day of bleeding is the beginning of the menstrual cycle. At this time, the interval is generally about 28 to 30 days. It is normal to have menstruation three to seven days in advance. Generally, girls will have menstruation after their uterus develops well after entering puberty. Normally, it should be between 11 and 14 years old. Some people will have menstruation at the age of 18. Considering that everyone's physical condition is different, the time of menstruation varies from person to person.

The first day of bleeding is the beginning of the menstrual cycle, and the interval between the first days of two menstrual periods is called a menstrual cycle. It is generally 28 to 30 days, and 3 days earlier or later is still within the normal range. The length of the cycle varies from person to person, but each woman's menstrual cycle has its own regularity.

The changes in the menstrual cycle of women aged 20, 30, 40, and 50 are as follows:

20 years old: If dysmenorrhea during adolescence becomes more and more severe with age, it is very likely that there are abnormal conditions such as pelvic inflammatory disease, endometritis, endometriosis, etc. It is recommended to go to a regular hospital's gynecology department for relevant examinations and receive appropriate treatment when necessary.

30 years old: Menstruation at this age is the most regular stage in a woman's life. Compared with the dysmenorrhea problem at the age of 20, if in addition to dysmenorrhea, there is also pain during sexual intercourse, it should be noted that women in their 30s are more likely to be troubled by premenstrual syndrome. I have to go through a few days of sadness before each menstrual period. Dysmenorrhea and heavy menstrual flow in a 30-year-old woman may be symptoms of endometritis or uterine fibroids.

40 years old: The length of the menstrual cycle begins to change. It is normal for the cycle to change from 21 days to 35 days and then to 27 days. In addition, your menstrual flow may increase. Irregular bleeding that begins at age 40 may be a symptom of uterine polyps. Although the ovaries no longer ovulate as regularly as before and the frequency of ovulation has also decreased, the issue of contraception cannot be ignored. The rate of unplanned pregnancy for a 40-year-old woman is as high as that for a teenager.

50 years old: The menstrual cycle is mostly irregular, with varying lengths, and sometimes there will be irregular vaginal bleeding. Most people go through menopause 1 to 3 years after age 50. Because estrogen levels drop significantly during this period, perimenopausal symptoms such as bad temper, irritability, and restlessness may appear. During this period, the incidence of various reproductive tract tumors increases significantly; it is recommended to go to a regular hospital for regular physical examinations.
