I am so, so sorry to hear about this. I remember how excited you were to be pregnant again. I hope you are able to find out what happened.
I remember reading that Angie's MFM or OB told her that there could be clotting disorders that they don't have tests for, but I don't recall anyone testing normal and then finding out later they actually do have one.
