don't worry, i had my amino (抽胎水) done on tuesday. the procedure was fast and simple. the doctor just poked the needle through your tummy to get the "water". it stunk a little at the beginning but not too bad. i got the fast result the next day.
my oscar at first was far worst than your. it was 1:36, very high risk. the doctor recommanded me to do an amino instead of a cvs simply because it's safer. he also looked at the ultrasound result and the baby seemed normal, so he told me that i should do the amino instead.
you can do an amino at 16 weeks and i did it at a private clinic. i think it is worth it, even though it costs $4500, because you will know in 3 weeks if the baby has any genetic disease after they do a full profile of the dna.
hope it helps and good luck to you. don't worry and have faith in your baby!
I just received my own blood test results and my readings are very similar with yours:
Free BhcG 2.07 MoM
PAPP-A 0.40 MoM
NT: 1.2 mm
But as in your case, my blood test results failed and I've a relative high risk for T21, which is 1/122.
What should I do now? I got bleeding and spotting throughout my pregnancy. The doctor thus NOT recommending the CVS, so the only choice is needle test~~
