Hi, I m almost 100% sure I m not pregnant but I want an opinion. 5 weeks ago I was with a guy. We didn t have sex, but he came when we were both naked and I wasn t very careful cleaning up. For all I know something might have gotten where it shouldn t. But anyways, I had my period two weeks later and I can t currently remember if it was only a day or two, or more. Then just a few days ago I had super light spotting for a few hours and then nothing. I m waiting to get my period as it usually comes around now. A few days ago I got really nauseous at 3 am. Didn t vomit, but my stomach and abdomen were in pain and I wanted to puke. Last night at 5 same thing. I d feel just kinda sick, and five minutes be 100% certain I was going to puke (I never did), and five minutes after that be almost fine again. If it isn t pregnancy, any ideas as to what else it might be? Thanks!
