And they think it's a boy! The tech said she couldn't be certain because baby was curled up in a ball for most of it, but she thinks boy. Which matches what I thought after I saw the NT scan pic. It looks like a boy.
It was a pretty rotten experience in some ways, though. They wouldn't let my husband in until the very end, they wouldn't let me watch, and I had to sit, sweating, in a small, sauna-like cubicle, waiting for the tech to get me in the beginning. In the meantime, my husband was a bundle of nerves in the waiting room and was pretty grumpy by the time they came to get him, an hour later.
But it seems like everything is okay. The techs aren't allowed to tell us anything, though. And we have to go back in three weeks to get better pics of the heart. I'll probably find out more at my next OB app't on Wed.
But while the tech was out of the room, I looked at the screen and memorized the measurements. Everything was between 19 weeks and 19w3d, except for...femur length. They were measuring 20w2d! This is a TALL baby! (My husband is very tall as well, so not surprising, but I laughed when I saw that. When we talked to my MIL afterwards, she said that my husband was all legs and arms when he was born, which astonished even the doctor.)
