Ups and Downs Continue

Ok, this is the craziest journey I have ever been on!!! Went in for another HCG test today to verify that number is going back down and was in shock when nurse called to say that number had risen to 904! What the heck is going on? Why all the ups and downs? I've already grieved the loss of this baby and have started researching our next step - donor eggs. I don't "feel" pregnant anymore. The bleeding has slowed down considerably today. What does that mean? I am driving myself and Baby Daddy crazy with searching the internet every night looking for answers. This is enough to drive someone mad! Nurse suggested possible ectopic, but from everything I read, that doesn't seem to describe what's going on.
