What causes menstruation to come half a month early?

When women have irregular menstruation, they should pay attention to whether there are some problems with their bodies. If women's menstruation is early, delayed, or the menstrual volume is small, it may be caused by some problems in the body. Therefore, a physical examination should be carried out at this time to have some understanding of the physical condition. When problems arise, they can be improved in time. What is the reason for menstruation to be half a month early?

Many women are not very clear about the reason why their menstruation comes half a month early. When this happens, women should pay attention to whether there are any abnormalities. If so, they should go to the hospital for examination in time.

What are the reasons for early menstruation?

The normal menstrual cycle of women is about 28 days. If the menstrual cycle is always more than 7 days early, or even occurs twice within a month, it is called "early menstrual cycle", also known as "early menstruation" or "early menstruation". If it is only 3-5 days ahead of schedule and there are no other significant symptoms, it is within the normal range. Occasionally, the menstrual period comes ahead of schedule, but it is not considered as an early menstrual period.

Therefore, if menstruation comes 10 days early only occasionally, it is generally not a big deal. But if menstruation comes 10 days early every time, it may not be normal and you need to go to the hospital for a thorough check-up.

If menstruation comes half a month earlier, it may be caused by luteal insufficiency. This disease often occurs during the childbearing age because the relatively fixed luteal phase becomes shorter, which shortens the menstrual cycle. It may also be dysfunctional uterine bleeding during adolescence, which is caused by the incomplete development of the hypothalamic-pituitary-ovarian function. Alternatively, if menstruation occurs half a month earlier, it may be menopausal dysfunctional uterine bleeding, which is caused by ovarian dysfunction. If you are over 35 years old and your period comes half a month earlier, it is most likely caused by poor ovarian reserve function; some women with heavy ovulation bleeding may also experience frequent menstruation. In addition, severe uterine fibroids may also cause heavy menstruation, frequent menstruation or shortened menstrual cycles.

The above is a detailed introduction to the reasons why menstruation comes half a month early. For women, if their menstruation is early, there is no problem if it does not happen often. If it happens often, it is very likely that the woman has a gynecological disease. In addition, for women who have black hair during menstruation, women should also pay attention to some conditioning and arrange a reasonable diet.
