I had the same scare. They told me my baby could have down syndrome. I looked into the risks for the amniocentesis. I would never abort my baby, regardless of the results, but I feel that a lot of preparation is in order if I have a baby with special needs. I did have the amniocentesis test and am awaiting the results. (should have the in 2 days) They test was a scary thing, the needle is huge, but at the same time, the specialist the did it had a 3D ultrasound running the entire time so we saw exactly what my baby was up to. I did leak a little amniotic fluid a couple of days after the test, which scared the crap out of me, but all is good, now. No one can tell you whether or not to have the test, it is a scary one to have, but I know I will be ready and able when my baby boy is born for what condition he has, if any. Mainly, if I wondered the entire 19 weeks of the rest of my pregnancy, I would ultimately stress myself to the point of sickness - which is also not good for the baby. The percentages I have been told and have found on my own research are all different, from wha t is listed in the submissions in this blog to what my doctor told me to across the board on the internet. From what I can gather, the blood screening results are between 60-80% accurate. The amnio is 99.9% accurate. The risk is 0.05% of miscarraige or damage to your child in the procedure. Good luck to you all and love you baby, no matter what! I know I will!
