Hi H.-
My 2 pregnancies were wrought with uncertainty. I know the waiting time from test to test can be an eternity, to put it mildly. It is okay to ask the MD what the concerns would be given the difference they are seeing. Avoid researching on the internet-there is a lot of incorrect info and it will do nothing but add to any anxiety. Try not to allow yourself to play "tapes" in your head of scarey, worried "what if" thoughts. It does no good. Keep telling yourself, "this will be okay". I wish you well and try to stay peaceful.
