Our little girl was very cooperative during the ultrasound. In fact, they said they could use the ultrasound pictures for a textbook. She looked perfectly healthy and gave us some great pictures. I am 21 weeks and 1 day today and she measured (based on head and arm/leg bone measurement averages) 21 weeks 3 days. They said that they like to see the baby measuring a little more than the actual gestational age, so that was also good news.
They provided us with a DVD and lots of pictures. For our family and friends who are interested, below is part of the video of the Ultrasound that I just uploaded to youtube. Enjoy!
