Im very worried about this sooo please answer back at me... Me and my bf were messing around one night and I didnt have my panties on.. He had his underwear on and a pair of sheer basketball shorts on.. Well he was on top of me imitating sex.. I felt wettness on his shorts close to his area.. Im on birth contol but I was taking amoxicillin at the time.. Is there a chance I could be pregnant?
