Want to cry

I want to cry. I feel like i might. I have been very nauseated and vomiting. I am having a ton of cramping. I have been having increased clear discharge. I am completely miserable and getting very easily dizzy. And now I know I am not pregnant. Or at least that my HCG is 0. Not even a hint of being pregnant. I don't have a UTI either. What the hell is wrong with me? Am I crazy. I now have my husband so concerned for me that he has started saying lets stop trying if this is how bad it is going to be. I want to cry this is just miserable. I want to crawl into a hole and sink int the ground.
