what's happening to me

I just got over my period not too long ago, and had sex during my Peak two weeks ago. the last 4 days my stomach has been really hurting me, I've been nauseous almost constantly, and especially while near food. I also have no appetite. I've literally been forcing myself to eat food, while feeling sick while doing it. Over the weekend once, Yesterday Once and today twice, I've gone to the restroom and when I wiped I had blood clots, but no actual blood. I have not gotten my period yet, and it is way too soon for me to be getting it again. at least I think so...
