So im getting ready to start my period and i feel a pain when i pee so i drink cranberry juice because im used to getting bladder infections when my period comes around. Well it cleared up and the next day ( the day before im supposed to start my period ) I had sex with my boyfriend. We didnt use protection but he pulls out . and i know there is still a risk but he can actually control himself unlike most. Still i know there is a risk . the next day i dont start and instead i start to fill like i have discomfort when i pee and what not .... What is going on ???? Am i now stressing to much that it will prolong my period if i am not pregnant??? I just need some info please ...
