Hi! My boyfriend and I had sex 3 weeks ago. I am on birth control so I know when my period is coming. I missed a pill and had to take it the next day. We had sex again while I was taking the placebo pills and my period had not started yet. The condom broke and I took the morning after pill. Today is the last day of my pills I start a new pack tomorrow and have not had my period. Could the morning after pill affected my period?
