My anatomy scan possibly showed a risk of 1/500 that my little guy has downs syndrome. The scan wasn't conclusive, and I have to go in for another one early next week, so what I'm wondering is,

Has anyone else been told there is a risk, and then gone in for more testing and been given the all clear?

I feel it in my bones that he is 100% healthy, but until I know for sure my mind is going to be running a mile a minute. Any advice is wanted.
