Early menstruation is not a sign of aging. Normally it is normal for menstruation to be early or late within a week. The decline of ovarian function is a sign of aging, but usually the decline of ovarian function will make the level of estrogen and progesterone decline, the patient will have a delayed rather than early menstruation, and the decline of ovarian function will also easily lead to a decrease in the amount of menstruation. It is not normal for a woman to experience ovarian failure before the age of 40. The normal menstrual cycle is usually 23 to 28 days, as long as the menstrual cycle is more than 23 days, it is not considered to be early, and generally can not be interfered with. If the patient’s menstrual cycle is more than 10 days early, or if there is constant bleeding, the patient needs to go to the hospital as soon as possible to find out the cause of the problem and then treat it. If menstruation is seriously early or late for a long period of time, it is recommended that the patient go to the hospital for endocrine hormone and other related examinations to prevent abnormalities caused by diseases, and to detect them in time and treat them under the guidance of the doctor.
