Pictures of signs of menarche

In puberty, women's uterine wall undergoes regular changes due to the action of sex hormones secreted by the ovaries. It sheds once a month, and the shed mucosa and blood are discharged from the body through the vagina. This bleeding phenomenon is called menstruation. It is called menstruation because it occurs once a month for most people.

The first time a girl has her period is called menarche, which is one of the key signs of the onset of puberty. The age of menarche is approximately between 10 and 16 years old.

1. Before your period, there is usually some blood on your underwear.

Before a girl's menarche, her body will undergo a series of changes. If this change is understood, the time of a girl's menarche can be estimated.

2. Measure weight and height: After girls enter puberty (11-14 years old), measure their height and weight twice every six months. If a measurement reveals a sudden increase in height and weight, it indicates that the girl may have her first menstruation in the next six months.

3. Observe the condition of the breasts: If you find that the breasts have just begun to grow and develop, swell and nipples appear, and there is a lump when touched, then the girl will have her first menstruation in the next two years.

4. Check for secretions: If a transparent, colorless, odorless and slightly thick liquid like egg white is discharged from the girl's vagina, it is normal; if the secretions are dark brown, it indicates that the girl's menarche will come in 2-3 days.

5. If you have acne (acne on the cheeks and forehead with small pustules), your period may come within 2 to 3 months.

In clinical medicine, the onset of menarche in girls means that the development of the female body has entered a new stage. The first menstruation and the subsequent series of symptoms indicate that a series of changes have taken place in the female hormones. At this time, girls will develop acne on their faces. Acne is affected by the levels of estrogen and androgen and appears on the forehead, jaw and other parts of the body. At the same time, girls' breasts begin to grow and develop, and they can obviously feel the swelling of the breasts, and nipples gradually appear. In addition, before a girl's menarche, she will feel a subtle pain in her lower abdomen, which is a more obvious sign of her menarche.
