Thanks for the replies ladies.
Unfortunately I know exactly when I ovulated because it was a clomid cycle and I was temping as well as taking opk's. I think that is why my OB is concerned. He did say to keep my fingers crossed and that things may turn out to be ok...but the overwhelming feeling was one of "I don't think this pregnancy is viable".
I guess all I can do now is wait it out. I did take another preg test today and the line was extremely dark and I'm starting to have sore bb's. I'm not giving up yet. Every time I go to the toilet I'm scared I'm gonna see blood...but none so far. Keep your fingers crossed for me.
