First ultrasound was this morning (at around 5w3d). We have one yolk sack with a tiny little grain of rice inside. And it's in my uterus where it belongs!
Apparently, it's totally fine that there's no heartbeat yet. So I'm not going to worry for the next week. (aw, who am I kidding? I've already spent the last half hour searching for 5w3d ultrasound photos. Of course I'm going to worry.)
Anyway, next ultrasound is a week from Friday.
