So I was supposed to get my period this past week, but didnt!! Iv been really stressed the past week to 2 weeks and am wondering if that had anything to do with it???? I am not on birth control but my boyfriend and i always use condoms! the last time we had sex was right at the time i was supposed to ovulate! how likely is it that i might be pregnant even if we used a condom? I have taken a pregnancy test and it was negative, but i cant help but feel that somethin is not right!
