Elarwood- so sorry to hear :-( I don't know much about HCG levels but it sounds like you do. What did the clinic say? I know there's probably nothing we can say to make you feel better but if it's any consolation your definitely not the only one!! Heartbreaking. Hoping your HCG miraculously comes up. They took mine today at clinic but not sure i want to know, not sure how I'll take a negative.
