12 week 2 days NT scan

So I got my scan today at 12 weeks 2 days, and I got a call that the neck part they measure is 2.4mm.

I looked in my chart and no other markers for DS were checked just this one, but now they’re having me see a genetic doctor want me to do the nipt blood test (I skip all my pregnancy’s this is my 3rd) and a lot seems to be happening already.

Anyone have had similar and a positive outcome? I’m not really concerned surprisingly, but the way they’re acting has me more worried if anything. I feel fine about it and I truly don’t think I this is all too bad but they’re deff scaring me more.
