I am 39 and 30 weeks pregnant. I thought everything was going fine until 2 weeks ago, when my ob/gyn office called stating that the ultrasound that I took 6 weeks prior suggests that I get a fetal echo, and the nasal bone was not visualized. The place I took the ultrasound told me everything was fine and let me leave thinking all was great. I did do the echo 2 days later and thank god all went well. From everything I read, the nasal bone is #1 indicator of down syndrome. I had 2 other ultrasounds since, at 2 different places, one was definitive that they did not see nasal bone and the other wasn't sure. Upon speaking to other doctors, we realized that there were tests that I should have taken much earlier in my pregnancy, that my ob/gyn NEVER mentioned. Nuchal, ultrascreen, quad. He NEVER even took my blood. All they ever did was my urine, blood pressure and weight. He is totally negligent and he knows it. I have since switched doctors. I was offered now to do the amnio, which this late in the pregnancy, can cause complications. I am so scared. and so furious at my original ob/gyn for doing nothing on me, and for the ultrsound place for telling me everything looked great, and then I get a call a full 6 weeks later. God forbid if there is a problem, I could have and should have known, 3 or 4 months ago. I have been a wreck for 2 weeks now, thinking my baby has down syndrome. From what I read and am told, healthy babies have nasal bones visable on ultrasounds. Before all this happened we did the 3D ultrasound and he looks beautiful, but they said that down syndrome is not detectable on 3D's I may do the amnio when the baby gets a little bigger, but I am so afraid. Imagine putting yourself and your pregnancy in a doctors hands and then to be put in this position? Has anyone ever been told that they did not see the nasal bone on multiple ultrasounds then have gone on to have healthy babies? There are no other markers, and his heart is good. Please Advise. Sorry it's such a long read.
