What to do when bleeding occurs again 10 days after the end of menstruation depends on the patient’s specific situation. If the patient usually has regular menstruation without abnormal bleeding, and the bleeding occurs 10 days after the end of the current menstrual period, with a very small amount of bleeding and no abdominal pain or other discomforts, then it is considered to be ovulation bleeding. The patient does not need to do any treatment, just need to continue to observe. If the bleeding clears within 3-5 days, there is no problem. If the patient has heavy vaginal bleeding 10 days after the end of menstruation, accompanied by abdominal pain, lumbago or abnormal vaginal discharge and other discomforts, an examination is needed to determine the cause of the bleeding. Patients need to do ultrasound, gynecological internal examination and other preliminary screening, if necessary, need to do cervical screening or hysteroscopy to rule out neoplastic lesions. If the bleeding is caused by inflammatory diseases, anti-inflammatory treatment is needed. If the bleeding is caused by polyps or submucosal leiomyoma, surgery is needed to remove them. If the bleeding is caused by a neoplastic disease, the treatment plan will be chosen according to the stage of the tumor.
