Hi, I had unprotected sex with my boyfriend the day I finished my period and he finished inside of me so I went and took the plan B pill the next morning. 4 days later I started experiencing bleeding, enough to make me think it was my period again even though I am not supposed to get it for 3 more weeks and we had unprotected sex again while I was experiencing this abnormal bleeding. Is it possible that I can get pregnant with this bleeding and is it okay to take the plan B pill twice in one week?
