Possible pregnancy??

Okay so, me and my bf always use the pull out method and I know that's not real contraceptive and there's always a chance of pregnancy but that's just what we always done and never had a problem with it, he's extremely good at it. BUT you mix alcohol with that and mistakes are made lol. I'm very ovulated right now and Friday night we had sex and I was kinda half on top of him and I didnt know he was about to cum, he tried to tell me and move me but I didn't move in time and he came some inside me and some out of me. It wouldn't be the end of the world if I were pregnant but is there a good chance that I could not be too? I bought a test but I can't take it for another week.
