me and my girlfriend had sex in a pool on wednesday. im 95% sure i didnt cum and it didnt last long at all. the day after she began to worry that she may be pregnant. tomorrow she is gonna take the plan b pill. (after 72 hours i know, but ive seen 120 and it couldnt hurt) her period is supposed to start on wednesday. i dont think she is because i didnt cum but im starting to worry about it. what are the odds that she is pregnant?
