After a hysteroscopy, bleeding usually lasts for 3-7 days, and bleeding does not last longer than 7 days. If the bleeding time is more than 7 days, it may indicate the occurrence of infection in the uterine cavity, and it is recommended to take oral anti-inflammatory drugs and hemostatic drugs to help stop bleeding. At the same time, the amount of bleeding will not be greater than the amount of menstruation, if the amount of bleeding is greater than the amount of menstruation, it may suggest that there is an abnormal situation of endometrial shedding. At this time, it is recommended to go to the hospital for anti-inflammatory and hemostatic treatment to contract the uterus, which can help prevent infection and reduce anemia. After the hysteroscopy examination, it is necessary to prohibit coitus for half a month, to avoid early coitus and cause cross-infection. At the same time, we should also pay attention to good personal hygiene, vulvar hygiene, and also to avoid causing vaginitis, which ultimately leads to the occurrence of upstream infection.
