My period is usually for 5 days. But for several months now, i only experience heavy flow on the first 2 days while the rest of the days are completely light flow and Sometimea none. Blood flows only when i urinate or when i move into a certain position. The color of the blood on the rest of the days is darkish brown like a dark chocolate. Is it normal? Can someone tell me? I really need to know before going to a gynecologist .
