Is my girlfriend pregnant?

Me and my girlfriend had sex for the first time at the weekend, I didn't ejaculate inside of her and I pulled out way before I even felt like ejaculating, but we didn't use a condom and she had already made me ejaculate about an hour beforehand, I am worried about the chances of her getting pregnant from precum carrying sperm to her vagina, please reply as fast as possible, thanks

From what I just read online about it, pregnancy is not likely but it could still happen. The chances are low. It depends if the sperm is live when carried to the vagina. It is possible to carry live, leftover sperm during pre-ejaculation. If you went to the bathroom between sessions, the chance gets even lower because acidic environments help to kill leftover sperm in the urethra.

From my experiences, I'd say the chances are slim. It's possible, but not too likely. I mean, if it's not something you're trying for (pregnancy), then obviously you'll want to take precautionary measures. Of course, I think there's a certain line most of us draw in the name of pleasure. You can only prepare so much when it comes to good lovemaking, that's just the way it is. But if you're concerned right now, remember that the next time something like this comes up. Try to be more careful next time. You can always buy an error-proof test also.
