my boyfriend and i had unprotected sex. i took the plan b pill two days after having sex. i had also just finished my regular period a week prior to having sex. here we are almost two weeks later and im still bleeding. it began as almost a darkish brown, then bright red, then it looked like it was gonna stop and just came right back. im suppose to begin my regular sched period next week. could this bleeding be due to the fact that this is also considered my period. im getting all the effects.... breast tenderness, back pain, cramping, nausea. is this normal or should i make an appt with my dr?
