... way at least 3 months ago) and Last month I had brown discharge and some blood way early. I was still in the middle of the blue pills. This month however I am now onto another packs sugar pills and three days in I have not had my period. I am having slight lower stomach cramps. Is this normal? I was put on the birth control to help my periods (they would be so heavy I would pass out). I have also had sex this month. Would that have anything to do with me being late? Is pregnancy a possibility?
