I am on birth control and today I took my last actually (blue) birth control pill and tomorrow I am supposed to start the white (period) pills. I never skip any pills and I take it about the same time every day (normally at 2:30) but no later or earlier than 30 minutes before or 20 minutes after. I had sex and he accidentally came on himself and possibly in me (but not sure). If I have my period in the next couple days could I still possibly be pregnant?? Do you think there is any chance at all I'm pregnant??
