Why weren't you using protection. If you cum, there is always a chance of the girl getting pregnant even if you take it out right away. Because if the slightest bit gets in her, it can swim up. Sperm is alive. I suggest you use protection next time. Hope I could help! [: <3
Yes, there is a possibility. The pre-ejaculate (pre-cum) has sperm in it as well, so there is a distinct possibility of her getting pregnant. The pull out method has never been considered a safe birth control method. You should invest in condoms OR not have sex.
