Hi... i'm a 19 years tennage girl and i have a serious question. Last month i had sex with my bf and for 3 times in 3 different days the condom broke after 6 or 7 mins. After all that 3 times i didn't took any plan b pills or anything. I also don't take regular pills i always used just condoms. My period should be here next week but i'm afraid that it might not be. How big are the changes to be pregnant?
