How long does it take for a little girl to have her period after her breasts develop?

After a little girl's breasts develop, she will start menstruating. This is called menarche. Most of the time, it occurs around the age of 12. If it is too early or too late, it will be very bad for the body. This shows that the development is not so complete, and there may even be symptoms of precocious puberty. If this is the case, relevant treatment is needed to improve.

Menarche and subsequent menstruation may not occur with ovulation. But there are rare cases where ovulation occurs one to two weeks before menarche.

The average age of first menstruation for Oriental women is between 12 and 16 years old. The statistics in different countries vary slightly, which is related to eating habits and climate.

In rare cases, menarche occurs very early, before breast development and other pubertal development. This symptom is called "premature menarche". Other possible causes of bleeding must be ruled out before diagnosing this symptom.

If menarche does not occur more than three years after breast development, it is called primary amenorrhea. About 30% of primary amenorrhea is related to genetic abnormalities, resulting in poor gonadal function or incomplete development of reproductive organs. Anatomically, the closure of the hymen causes amenorrhea.

Some women have their first menstruation at age eighteen, but it is generally believed that if you have not had your first menstruation by age sixteen, you should consult a doctor. The cause of late menstruation may be being underweight or overweight. Both of these reasons are due to the low and high proportion of body fat, which affects the normal physiological function of the ovaries and causes late menstruation. In addition, the normal function of the pituitary gland that controls endocrine system, tumors in reproductive-related glands, medication, mental stress, etc. will all affect the timing of the first menstruation.

Menarche is considered by most women to be an important "milestone" in puberty.

It is very important to strengthen physical and mental health care and women's health counseling for girls experiencing menarche.

First, parents (especially mothers) and teachers should teach girls who are experiencing menarche about the physiology and sexual psychology of adolescence, so that they understand that menarche is an inevitable part of physical development and a sign of entering puberty, and there is no need to worry. At the same time, they should be made aware that low back pain, drowsiness, fatigue, and weakness that occur during menarche are normal phenomena, so as to avoid panic and increase the psychological burden.
