Paul and I went to the geneticist today, and had another ultrasound. Between some blood samples and some measurements on the ultrasound, they were able to minimize the chances of the baby having a choromosomal defect to 1:2000, or better. Since our odds of defect are the same as a 20-year-old girl, we have decided not to have the more invasive procedures (amniocentesis or CVS), since they have a greater risk of miscarriage than our risk of defects at this point.
Needless to say, we are greatly relieved at today's results, and feel like we can move forward now with a more positive and excited outlook. I think we are probably over the biggest hurdles now! I think this one is a keeper!

During the ultrasound, we again heard the heartbeat (153 bpm today), and confirmed our due date of May 24. The baby is approximately 6 cm from "crown to rump" (not including those long legs). We also got to watch the baby for a minute as he/she kicked his momma, stretched, and squirmed around. We are going to try to capture the video digitally tonight, and (if successful) will post it shortly as well.
Sidebar: After today's video, I definitely think a little differently about the whole abortion issue -- I still think it should be the parent's / mother's choice, but I had no idea how active and vital a 2 inch fetus was in the womb. I guess I thought it "just laid there" until later in pregnancy, but today we saw ours move like a typical baby moves, and it was quite amazing... I am so glad our news today was positive, and we don't have to make any tough decisions.
