I had unprotected sex Friday, Saturday, and this morning. I am on birth control but I missed Friday and Saturdays pills on my first row of the pack. I'm gonna have to miss today's pill and also tomorrows pills cause I won't have a way home until Tuesday. If I miss this many pills I will probably start my period. If I do start and I'm only half way through the pack could I get pregnant. Even if I do start my period. I'm confused and concerned. Please help
