I am 39 years old and almost 35 weeks pregnant. My original ob/gyn gave me NO prenatal tests, not even blood work was done. I had a 20 week anatomic scan and was told everything looked great. 7 full weeks later I was told to have a fetal echo, and that they did not see the nasal bone. Fetal echo was normal. I had another ultrasound at 27 weeks again told no nasal bone visualized. I have since switched doctors and have been a total wreck thinking my baby has down syndrome. From everything I read on the internet, it's guaranteed. There are no other markers, and for some reason, my new doctor is not worried. I had a 3d and 4d sonogram done at 28 weeks and he looks perfect. I have over 200 pics and a 45 minute dvd, and no anomalies are seen. Is it possible for a baby to have either no nasal bone or a very small one and not have down sy ndrome? Please, if you could help me, I would so appreciate it. I have been going through hell.
