Signs before menstruation in primary school students

Women usually start menstruating at the age of 12-16. Most people start menstruating when they are in middle school, but some girls who grow faster start menstruating in elementary and middle school. So what are the signs of menstruation for elementary and middle school students?

1. Increase appetite

If the appetite of primary and secondary school students suddenly becomes bigger than before, and they want to eat before they reach the restaurant, this may be one of the main manifestations of the upcoming menstruation, which is affected by the changes in human hormones.

2. Increase in height and weight

Generally, the growth rate of height and weight of primary and secondary school students is similar to that of people of the same age, and it is very rare for them to have their first period in primary and secondary school. However, if a primary and secondary school student in your family suddenly grows taller and weighs much more than before, and the change is obvious compared with people of the same age, it may be that he is about to have his first period.

3. Breast development and pain

It is very rare for primary and secondary school students to have their breasts begin to grow. If there is breast enlargement, bulging, or pain when touched, these may be manifestations before the first menstruation. The body is affected by estrogen and breast enlargement occurs.

4.Growing male pubic hair and armpit hair

The growth of pubic hair and armpit hair is also affected by estrogen. Therefore, if primary and secondary school students grow pubic hair and armpit hair, and the color becomes darker, then you should prepare sanitary napkins for the children, indicating that the first menstruation is about to come.

5. Wearing things on underwear

Children's underwear is generally relatively comfortable, but if the first menstruation is about to come, under the influence of endocrine, female secretions will increase, which is manifested in the appearance of light gray secretions on the underwear.

How long does it take for menstruation to come after armpit hair starts to grow?

Everyone's situation is different, probably 1-2 years.

The growth of armpit hair is related to the secretion of estrogen and androgen in the human body. Generally, children between the ages of 12 and 15 will begin to grow armpit hair, which also indicates that the child has entered puberty. However, due to differences in genetics, nutrition, growth environment, etc., it is uncertain how long it will take for everyone to have their period after growing armpit hair, and it is estimated to be within 1-2 years.
