My boyfriend an i had unprotected sex last night and used the withdrawal method. We always use condoms when we have sex, but he also always pulls out when he feels he is close to ejaculating, even in condoms, and hes gotten really good at it and is aware of when he's close. He used the bathroom before we had sex, so i think there's less of a chance of there being sperm in his pre-ejaculatory fluid. He was only in for a few minutes and pulled out and a second after he pulled out said he felt like he was close and a few seconds later ejaculated, but no where near me, so i trust that he pulled out on time. I also went into the bathroom right after that and wiped down there. I have my period every 1-2 of every month (I've had regular periods since last year), so I'm expecting mine in 2-3 days. What are my chances of getting pregnant? I'm too afraid to ask my parents to get Plan B and I'm really scared!
