first u/s didn't go well XP
I had my first u/s this afternoon and there's just a sac. It measures right on for 7w, but it was obvious to me it was empty even before I was told. So, now we're waiting. I have a repeat u/s on the 14th, if nothing happens by then. But, I know it's just a matter of time. I'm surprisingly okay with it. We'll get past this (unless something miraculous happens and a baby appears in the next 12 days) and then we'll try again at some point.
ETA: now if only the m/s would disappear... I'm really looking forward to that!
