I'm 16 and two nights ago I had sex with a friend. It was a drunken mistake of course. But besides that I'm a little worried. We used a condom and he didn't cum in me at all. But I've researched a lot and with all the different answers I've seen I'm really worried. The only thing I've noticed is that I have a headache but I also had one yesterday and I do get them a lot. There's no swelling in my boobs or soreness and I'm not peeing more than usual etc. Basically there's no signs but my period isn't due for another 2 weeks and I'd just like some peace of mind I guess. I know there's pills and stuff but I'm not sure they'll be in my reach and I have a pregnancy test but I don't want to use it yet. I'm pretty sure the condom didn't break but it was my second time and his first and I'm scared that somewhere we made a mistake. I know that it's not unusual for girls to be worried afterwards but no matter how much I remind myself that we used a condom and he didn't cum in me I can't help but get stressed about it.
