My boyfriend and i had sex yesterday.we used a condom and it didn't break.i finished my period that day. he didn't ejaculate inside. can i be pregnant?

Unlikely: It is unlikely that conception would occur in the situation that you described above. Ovulation usually doesn't occur after ending a normal menstrual cycle. Normal menstrual bleeding occurs only for about 3 to 5 days. Without a condom breaking the possibility of sperm entering into the vaginal canal is minimal.

Unlikely: If you have regular menstrual cycles, and you were just finishing your normal period, you would not have gotten pregnant. I commend you for practicing safe sex, though. Always use a condom!
