Everything went perfectly. Scrappy showed a beautiful strong heartbeat of 161bpm and measured ahead by a couple of days. Notably, however, Dr. T said that when you measure CTR (crown-to-rump) length after 12 weeks it's not as accurate as it was earlier in the pregnancy. At 12 weeks they start measuring fetal head diameter, etc. to measure size. Regardless, Scrappy was the right size, and looked just as he should.
One of the best parts of the ultrasound was when Dr. T said, "Oh yeah, this one's a sticker!".
Music to my ears.
My next ultrasound is March 25th (at 19 weeks) and we'll hopefully find out the gender!
