When a woman has her period, the normal cycle is 3-7 days, and it clears within 7 days at most. However, if the menstruation does not clear in more than 7 days, there may be inflammation, endocrine hormone abnormalities, including bilateral abnormalities in the adnexa, which may cause dripping menstruation. If this is the case, it is recommended to go to the gynecology department for a gynecological ultrasound examination to determine the condition of the endometrium, including whether there are any abnormalities in the bilateral adnexa, and to take certain oral anti-inflammatory and hemostatic medications according to the situation. If the menstruation ends within 3-7 days, there is no big problem. Pay attention to personal hygiene during menstruation, and try to change your underwear every day to avoid cross-infection, which may cause inflammation. Pay attention to good warmth measures to avoid getting cold which can also cause severe abdominal pain.
