Good post Flowerchild.

When I got a high NT measurement they spent a lot of time looking at the nasal bone which fortunately was present which helped ease my worry a little, but I still chose to have an amnio just to make sure (1/37 chance of DS). It's one of those things you just don't know what you'd do until you are faced with the decision to know more about your pregnancy. You may think you wouldn't have invasive testing, but most women who are faced with a high risk of a chromosonal issue do actually go on and have it done. It would be incredibly hard to go through the pregnancy without knowing one way or the other.

Most DS bubs are actually born to women in their twenties even though their risk is much lower than women in their late 30's or in their 40's. This is thought to be because many women in that agegroup don't get the NT test done, nor do they usually go for invasive testing like most women over 35 do (and often go on to terminate if a trisomy is detected).
