If you bleed after 7 days of menstruation, you should consider ovulatory bleeding. Because the normal menstrual period is about 7 days, plus 7 days clean, which is exactly 14 days, in the ovulation period. Generally, the bleeding during ovulation is very small and clears in 3-4 days, so treatment is not needed when it occurs occasionally. If it occurs 3 times in a row, gynecological ultrasound and internal gynecological examination are needed to exclude organic lesions. If the patient bleeds 7 days after the menstrual period, the amount of bleeding is more or the duration of bleeding is longer, it is abnormal bleeding. In this case, inflammatory diseases, endocrine disorder diseases, polyp diseases or tumor diseases are mainly considered. Selective related examinations, such as cervical cancer screening, endometrial cancer screening, gynecological examination, gynecological ultrasound, etc., need to be done according to the patient’s specific condition.
