Well me and my girlfriend have been having sex for a while. She stopped taking birth control last month and we figured a condom would be enough protection. Well we got caught up in the moment one night and didn't have a condom. We didn't really have sex that night, we just tried without a condom a couple of times just to see how it felt. Now 3 weeks later she seems to always be exhausted. I mean she work from 7-5 almost everyday. Should I be really worried? I mean I haven't really slept good for a couple days and I think I might just be over reacting but I guess I need someone to tell me that.
