My boyfriend and I started having sex not too long ago. We use condoms and always check often to make sure there is no rips or breaks. I don't think it broke but and my period was supposed to start 2 days ago but didnt. However, I have been under a LOT of stress lately to the point were my boyfriend noticed that i havent smiled, eaten, or slept much in a week and a half. (cycle averaged 32 days its day 34) Im always paranoid that i will get pregnant. Do i have reason to worry? If so what are the chances i am?
