It is normal for your period to be 3-5 days early every month. A menstrual cycle between 21-35 days is normal. The menstrual cycle has a lot to do with the hormonal secretion of the ovaries, but everyone’s cycle is different, most women are around 28-30 days, but some people do have early or delayed periods, as long as the early or delayed period does not exceed one week is normal. For patients with early menstruation, there is usually no need for special treatment, as long as they pay attention to hygiene during their periods. At the same time, it is important to have regular gynecological examinations to understand the condition of the uterus, and to pay attention to the prevention of inflammation in general.
