The brown leucorrhea on the second day of intercourse, excluding bleeding caused by a small amount of endometrial shedding before and after menstruation, is mainly considered to be related to intercourse stimulation, ovulatory bleeding, cervical lesions, uterine inflammation and other factors. Patients should be treated according to medical advice and pay attention to a light diet and moderate exercise to promote physical recovery.1. Intercourse stimulation: Improper intercourse can lead to a small amount of breakage of the cervical mucosa and vaginal surface mucosa, resulting in bleeding, when the leucorrhoea is manifested with brown discharge. If the patient has no other uncomfortable symptoms, he can wait for his natural healing. During this period, the patient should avoid intercourse to avoid infection caused by germs entering through the rupture. 2. Ovulatory bleeding: If the patient is in ovulation, the possibility of ovulatory bleeding should be considered. After a mature follicle ruptures and ovulates, the estrogen level in the patient’s body briefly decreases and is unable to maintain the growth of the endometrium, causing local ulceration and shedding of the endometrial surface layer, which in turn causes bleeding. This can be treated by medication, such as hirsutestrol. 3. Cervical lesions: High-level intraepithelial lesions of the cervix or cervical cancer are prone to contact bleeding, which is also known as bleeding after intercourse. lead to vaginal bleeding.
