HCG went down, impending miscarriage?

Alicia

I had my first blood draw on Tuesday at 3 weeks 5 days and got a 33. The doctor said that was great and to have me back Thursday for a repeat. I got a call yesterday and was told that my numbers went down which means this pregnancy is non viable and I should expect a miscarriage. Getting that news, I blanked and forgot to ask how much my numbers went down. Is it possible that there was a mistake? I feel completely fine. I don't have any cramping or bleeding. I go back Monday for another blood draw to make sure my numbers are dropping back to 0 and I guess I'm hoping to see an increase instead. I don't want to give myself false hope. Has anyone been through this?
