When is it normal for a girl to get her period?

“Auntie” generally refers to female menstruation, and girls begin menstruating around the age of 13 to 14. Girls who menstruate too early or too late need to be vigilant.
Menstruation is a normal part of a girl’s growth and development. The first menstrual period is called menarche, and it occurs between the ages of 13 and 14. However, due to genetic, nutritional and weight factors, the earliest age at which a girl can have her first menstrual period may be 11 years old, and the latest age at which a girl can have her first menstrual period may be 15 years old.
The onset of menstruation is a sign of maturation of all female signs. During this period, the endocrine system, genitals and body will gradually develop to a mature stage, and the female secondary sexual characteristics will also develop gradually, with the appearance of breast development, pubic hair, armpit hair, etc. However, if a girl has her first menstruation too early or too late, she may have her first menstruation at the earliest age of 11 years old.
However, if a girl menstruates too early or too late, she should go to the hospital in time to complete the relevant examinations and follow the doctor’s instructions for a clear diagnosis and active treatment.
