At what age is it normal for menstruation to start?

Every woman has her period. The first menstruation of a beautiful girl is called menarche. Generally speaking, a girl's first period occurs during puberty. Due to the influence of many factors, the conditions of a girl's first menstruation will also be different. So how old is the most normal age for a girl to have her first menstruation? When does a girl's first period usually last?

The age of menarche is affected by health status and physiological growth and development. Those with good health status and physiological growth and development have a younger age of menarche, and vice versa, the age of menarche can be delayed. According to relevant information, the age of menarche for women in my country ranges from 13 to 15 years old. If a girl starts her period before the age of ten, she is considered to have precocious puberty. If a girl has not had her period by the age of 18, she may have primary amenorrhea, which is an abnormal condition and she should go to the hospital for a physical examination immediately.

Generally speaking, it takes about 2 years for a girl's first menstruation to become a normal physiological cycle. That is to say, if a girl's menstruation is delayed within 1-2 years of her first menstruation, or her menstruation is long or short, these are all within the normal range and there is no need to worry too much.

Generally speaking, a girl’s first period usually lasts about 2-10 days. ‍This is because the time of menarche for girls varies from person to person. For some, it may be over in two days, while for others, it may last about ten days. This is mainly because when a girl has her first menstruation, her uterus and ovaries are not yet fully developed, and her endocrine system may be disordered, which will lead to different menstrual periods.

Although all women have their periods, they may not know enough about menarche. However, parents with girls should fully understand the girls' menarche. The color of the menstrual blood of girls is usually dark red or white, and usually it will not be black or gold. If the first menstrual bleeding is less and the menstrual blood is black, it may be that the girl's physique is more yin-deficient and internally hot, and there is also a problem of deficiency of both qi and blood. At this time, parents should take care of their children in time.
