If the patient has taken contraceptive pills four times in a year, it is necessary to choose the appropriate treatment in the light of the patient’s specific condition, as well as the results of the relevant examinations. If the patient has a shortened menstrual cycle, a significant increase in menstrual flow, and persistent vaginal bleeding, she needs to go to the Obstetrics and Gynecology Department of the hospital in time for an ultrasound examination of the uterus and ovaries, and a sex hormone measurement examination. If endometrial hyperplasia occurs, you can choose to scrape the uterus and send the scraped out endometrium for pathologic biopsy. If the patient has no obvious clinical symptoms and signs, the menstrual cycle and the color and amount of menstruation are normal, there is no need for treatment, and it is recommended that the patient should not take contraceptive pills more than three times in a year.
