My boyfriend and I had unprotected sex four consecutive times a night. I took the morning after pill(2 pills) two hours after the fouth round . Since we are both studying and are not ready for a baby I was so paranoid that I took another one ( 2 pills) seven hours later. Now my period is seven days late . We never had unprotected sex again since then. Could I be pregnant ? Or its just stress and be paranoid ?
