I have continuous bleeding which i suspect is not my menstruation. A few days ago. I had lower left abdominal pain which is like i was having my menstruation but it is of higher pain but tolerable on the 3rd day but 3 days before that I had fever and weakness. On the 4th day i had a menstruation like bleed but it is brownish in color. The menstruation stopped and the next day in the evening it appeared and again stopped and on the 3rd day menstrual bleed appeared. It has been 5 days already and i thought the menstruation is finished because the bleeding is brownish but then again i see fresh blood coming out from time to time. What does this mean? Could i be having miscarriage?
