Well - we saw all there was to see this morning - one yolk sac... nothing in the wrong place. It was way to early to see a heartbeat - so I go back on the 22nd for another u/s.
I was nervous for a bit - because the first part (the non-vaginal u/s) she didn't say anything. And I didn't have a good view of the screen. And then she left the room to get the doc for the vaginal u/s. And took a long time. I started to get nervous! But then she came back in with the doc, and he was super nice. They assured me that they weren't expecting to see anything except a yolk sac (which they did) and just wanted to be sure the other embryo wasn't lurking in a bad place (which it wasn't).
One hurdle over!
