Hello, Thanks for using health care magic Brown vaginal discharges are not normal and when particularly occurring after menses most often than not are an indication of a pelvic infection. Pelvic infections could are favored by menstrual blood since blood is a rich culture medium for bacteria. It could also be favored by unprotected sexual intercourse with unsafe partners. Pelvic infections can as well be a cause of difficulty in conceiving. You should meet a gynecologist for detail examination, investigations and follow up. Hope this helps you Best regards Dr Achuo
