Just had my 12 week ultrasound today (technically 11w5d). It was also a combined screening for chromosomal defects. I don't have the blood work back yet, so no risk estimate, but they saw a well defined nasal bone and the NT measurement was 1.3 mm which the technician said was very good. I was so surprised at how active the baby was. It was doing somersaults, waving and jumping around. It was hard for the technician to get it to sit still in the correct position for long enough to take the pictures. I'm attaching a couple pictures, and if anyone wants to take a shot at a gender guess please do! The picture quality isn't great because my scanner isn't very good. I don't see any nub there at all, but what do you think about the skull shape? I can't believe that 1st trimester is almost over!
