Everybody looks great! It didn't take nearly as long as they thought it might, and they got almost all the measurements they needed. Baby A refused to flip over so we could see her face, so they're going to take another look at her at our next appt. Here are some fun stats:
Baby A: girl, HR 163bpm, 13oz.
Baby B: boy, HR 153 bpm, 14oz.
Baby C: girl, HR 134 bpm, 13oz.
So I have 2.5 pounds of baby in me! The boy was definitely the most wiggly but also the most cooperative in terms of showing off all his parts. The girls were a little more shy.
My cervix is still looking strong at around 4cm.  
Also, I've gained nearly 35 pounds so far! The nutritionist is happy with that and wants me to keep gaining at the same rate in order to fatten up the babies.
So I can put aside my anxiety for awhile and focus on these good results. We'll start going in every 2 weeks now.
