Had unprotected sex the night I missed taking a pill....took two the next day but then a few days later forgot to take again and the day before I had unprotected sex 4 times....the next day doubled up....I have been using my pills to skip my periods and have had no bleeding and started a new pack....how likely is it I'm pregnant. Been nauseas and tired and my breasts feel fuller....I will get a test tomorrow when I'm off and get to the doctor Tuesday. This is just my first time using pills and I'm curious how terrible I messed up?
