13-year-old period came a little and then disappeared

The first menstruation is the first menstrual period for a girl and it is an important sign of the onset of puberty. The first menstruation means that the uterine wall is stimulated by estrogen and grows, which mainly means that the "passage" from the uterus to the cervix and vagina is opened. Most girls have their first menstruation at the age of 12-14, and a few have their first menstruation earlier than 10 or later than 19. Is it normal to have a period at 13 years old and then stop?

1. Is it normal for a girl to have a small menstrual flow at first?

Every girl will have her menstrual period when she reaches a certain stage of growth and development. However, when girls have their first menstruation, there is still some difference between it and the normal menstrual period.

1. Many girls have less menstrual flow during their first menstruation. This is because the girls have just entered their menstrual period, and the uterus, ovaries and other urinary systems have not yet fully developed. This is a normal situation, don't worry too much.

2. Because the menstrual period has just appeared, the female hypothalamus-pituitary-uterine-ovarian axis has yet to develop, so even if the menstrual period comes, there will generally be no ovulation, and the menstrual period will be relatively irregular. This is all very normal, and girls do not need to be anxious about it.

3. With the gradual growth and development of the body, girls' menstrual flow will gradually return to normal, and their menstrual cycle will become more regular. Therefore, scanty menstruation and menstrual irregularities are only temporary conditions.

When girls have their first menstruation, their menstrual flow may be too much or too little, which is normal. The menstrual period at this time cannot be compared with the menstruation of mature women.

2. How many days does it usually take for the first menstrual period to be clean?

When you have your first menstruation, it may not be as regular as a normal menstrual period, so don't worry too much when it is irregular, because the uterus and ovaries have not developed well at this time, so it will not be as regular as a normal menstrual period. How many days does the first menstrual period usually last? Let’s find out together.

1. Girls' menarche usually takes two to ten days. The actual time will vary according to one's physical condition. For some people, it may take two days to complete, while for others, it may take ten days. This is mainly because the uterus and ovaries are immature during the first menstruation, which can cause endocrine disorders.

2. Under normal circumstances, it takes about 2 years from the first menstruation to the normal menstrual cycle to restore the normal menstrual cycle. Some people's menstrual period is accelerated or delayed, while others have no delay. This is all normal physiological needs and there is no need to worry too much.

3. Menstrual irregularities during the first menstruation are all normal, unless there are some abnormal pathological reactions. At this time, you need to go to the hospital for examination and treatment according to the condition. However, in this case, the possibility of disease is very small, and it is usually because such a situation occurs when the uterus is underdeveloped.
