I'm pretty sure I'm in for bad news, but wanted some insight from those who may have been through this before, and those who may have success stories. I had my 7 week ultrasound today after transferring 3 day 3 embryos last month. The ultrasound tech found one baby measuring 6w3d. At first she couldn't find a heartbeat and then found one at 103. She says it wasn't beating sometimes and then it was. My RE (reproductive endocrinologist) seemed more optimistic and said there's a margin for the measurements and that when the embryo is that young and the heart is developing, the fact that the heartbeat was intermittent may not be such a bad sign. Since, it was IVF, we obviously know the dates were right. Any thoughts? Am I out of luck?
