Around 18 weeks we went in for our anatomy scan. They check all of the organs, facial features, weight and bone lengths. This is when they can tell if there are any heart defects or problems with brain development. The tech said they looked very good! One was 10 oz and one was 11oz. So basically I have 1lb 5oz of baby and who knows how many lbs of fluid. It's getting pretty heavy!!!
I went to the Dr. yesterday for my normal visit with my OB. He said everything is great and all of the tests came back normal (phew!). The boys are both doing well - he checked for their heartbeats on a quick ultrasound.
I go back in a month where they will schedule another anatomy ultrasound to make sure they are still both growing at the right pace. After that I believe I start going more often to check growth and positioning.
