i have a lot of questions could someone help me ? i was on a birth control car for almost a year & then I got it taken out two weeks ago and I had sex today unpertected & he cum inside me & I peed about two hours after wards . Is there a chance I might be pregnant . But we did have sex the 17th unpertected as well & for the past thre days my nipples have been sore& sinsitive . But since that birth control bar , I haven't really had my periods & I have had one since I've been off the birth control ? I'm so confused ? Could someone help me ?
