I'm 32, I'm finishing college this year, and i wait tables for a living. I don't want to be pregnant right now, and wonder if I'm making myself think I am out of anxiety. Right before my last period, i had unprotected sex with my long time boyfriend and was nervous the next day ofcourse. I started my period on schedule, about a week ago, but it only lasted about two-almost three full days. A bit shorter than usual. I don't use birth control so it isn't unusual for my period to vary a bit, but ofcourse I'm nervous, considering the fact we didn't use a condom, and I do not want to get pregnant any time soon. The last couple of days, i thought I had felt nausea off and on, but I'd also had some drinks for fourth of july. I'm not eating unusually and my breasts aren't sore at all since my period came and went. I've just been extremely preoccupied with the idea, and maybe this is making me think i feel symptoms, even creating nausea? Any ideas? When should I really be worried?
