I'm sorry! Hopefully the #'s will go up, i know the waiting is terrible.
Just know if it is another chemical, you are in good hands with Dr B. After my 2nd miscarriage He ran all the bloodwork to determine what was causing them. It can be something so simple like a pill or baby aspirin and then you will get your healthy pregnancy. I pray you wont even need to worry about that b/c hopefully everything will work out!!!!
