I take mononessa. I'm on the last week of my active pills and My schedule was thrown off this week. I took one pill a day late and forgot the last two active pills completely. I usually start my period on the third day of taking the inactive pills. But this time I started a day or two early. (I realize this is because I skipped the last two active pills) but my period is heavier than its ever been. And I have diarrhea. What is going on? Could I be pregnant?
