Sex in a pool and getting pregnant

Ana

My boyfriend and I were in the pool and he stuck his penis in once with out a condom. I know if you don't want to become pregnant than you should wear a condom but it just kinda happened. He didn't thrust really, all he did was pretty much stick it in. There was no fooling around before hand or anything so there was no build up or anything. Should I be scared about becoming pregannt? I'm on a 7.6% day.
