@LadyLouise, hang in there, it's all about the doubling. I wish I could find it, but one of the lovely ladies on the immune thread posted a link a few weeks ago to a study that was done to see variation in HCG for individuals in early preg and seriously the differences were massive-and these were successful pregnancies. Good hcgs can turn out badly and 'bad' can turn out well. I know probably impossibly hard but try and keep your mind off it over the weekend. Lots of treats are in order I think.
