I don't think it is possible to miscarry like that, but it is possible for the baby to not have a heartbeat at the first u/s. This happened to a very close friend to me. She went in for her 8 week u/s and there wasn't a heartbeat, but she hadn't miscarried yet. After she didn't have the miscarriage a week later, her doctor performed a DNC.
yes it is possible its not that they dont have bleeding it just hasnt started yet. i know of a women who got to see the heart beat at 8 weeks and went in for another ultra sound at 16 weeks and the baby had died two weeks earlier however her body had not yet physically miscarried even though the baby died. so yes she is right in what she tells you it can happen that was but eventually the body will bleed and if it doesnt the dr will have to remove it
