Hi K.,
I think it's wonderful you are not letting the test determine whether or not to keep your baby! What a lucky child he/she is. : )
When I was pregnant with my 3rd child I did the first trimester screening and also got a similar result like yours. The first sono came out normal and after doing blood work my OB called and sounded very concerned and encouraged me to do more testing. I was SHOCKED! I was 24 yrs old and thought there's no way possible at my age could my baby have down syndrome.
So I went in for the amnio (scared to death) and the amnio sono doctor told me my chances were around 1/200 so after doing the amnio I got my results back about a week later saying my baby did not have down.
I was relieved only because I do not think I was prepared to take care of a child with down at my age, having two other young children at home and the way my life was going at that time.
So, what did I learn from the test is that first, I will NEVER have the screening done with any other pregnancy because it's not worth all of the fear and worries I went through and second, I learned it is very common to get posotive results with your first screening which is why I don't understand why they're even doing the test anymore.
I think it causes to much stress and concerns on people even if they decide to keep their baby no matter what the result says, it still causes some worry.
I would advise you to not do the amnio if you are going to keep your baby no matter what the results are because as your baby grows, you can get level 2 sonos done that can also measure bone growth in the babys facial features which can help you know before birth if he/she has down.
Good luck and I wish you the best with your new blessing!
