At what age do girls get their periods?

Everyone has to experience puberty, and with the continuous improvement of living standards, children's daily diet has become much more nutritious, so there are often cases of girls puberty early, and everyone's physical condition is different, so everyone's puberty time is also different, so, at what age do girls usually start to have their periods? What are some growth and development rules for girls?

The time of every girl's first menstruation is different, so girls don't need to compare too much with others. When the menstruation comes, it will come naturally, and there is no need to have psychological burden.

The general age of first menstruation is between 13 and 15 years old. Some girls may have their first menstruation earlier, at 11-12 years old, while others may have their first menstruation later, at 17-18 years old. Affected by many internal and external factors, everyone's first menstruation age is different.

Because the age of a girl's menarche can reflect whether a woman is at risk of breast cancer (early menarche is often a high-risk factor for breast cancer) and whether a woman has primary amenorrhea, knowing when a girl will have her period is still of great clinical significance.

If you still have your period after the age of 18, please see a doctor immediately. Because girls' menarche is an important sign of the beginning of puberty, it is very important to understand the circumstances of girls' menarche.

What are the growth and development standards for adolescent girls?

1. Secret development process

This class is generally 8 to 11 years old. The glands and organs (eg uterus and ovaries) grow faster and begin to secrete testosterone. The hands and feet grow rapidly at this time, and the height increases.

2. Breast development

Breast growth and development generally occurs between the ages of 9 and 14. At first, the nipple bud, a small protrusion under the nipple, grows first (usually one side grows first and the other side grows later). Over the next few months or two, the nipples begin to grow and the breasts begin to enlarge. There is also a situation in which the human body grows rapidly, changes occur successively in various parts of the body, and height increases significantly.

When the breasts begin to grow, they may be accompanied by pain and discomfort.

Don't be anxious or worried at this time, pay attention to rest and nutrition, this is something every girl must experience, and don't develop a shy mentality. We need to promptly understand some knowledge about puberty, and have a certain understanding of our own body.

For a teenage girl, the changes in the body need to be accepted and adapted by herself. As long as it is a normal phenomenon in growth and development, we need to treat it with a correct mentality. During the period of breast development, be sure to wear cotton, breathable and loose underwear, and avoid tight ones.

3. Male pubic hair development process

This stage usually occurs after the breasts begin to grow. There are also 1/5 of girls who start to grow pubic hair after breast development, which is also normal. The pubic hair that grows first is straight and slender.

4. Girls’ menarche

One or two years after the breasts begin to develop, the menstrual period also arrives (medically known as the first menstruation). Most girls have their period at the age of 12 to 13, but for many it comes earlier or later, probably between 9 and 15 years old. There is a difference in time.
