I had my tubes tied two years ago after my c-section. My periods have been normal since then. Well I have had 2 periods this month. I recently came on Sunday and I normally have a 5 day period. Well It lasted for 3 days. My stomach been upset for two weeks now. I feel flutters. I thought it was a stomach virus but its not. Could I be pregnant. Mind you my doctor has had patients with tubal and they came back pregnant
