Nuchal translucency - opinions needed

Hi moms, I had my 9 week scan today and didn’t visit with my doctor afterwards. During the scan the tech was measuring an area on the baby and when I asked what it was she said the fluid behind baby’s neck. Well of course I went on google and realized this is a marker for Down’s syndrome. A lot of what I’m reading says it’s not really determined until 11-13 weeks, so I realize this is early/premature. I guess I’m just looking for stories of moms that had similar scans and what the outcome was. Did the fluid decrease at the 12 week scan, was it the same or more? And was the baby marked for DS?

Please don’t comment about if the baby has DS or not. I have a friend who has a child with DS and he is an amazing kid so I know what that’s like first hand. I’m just looking for advice on my situation.
