UPDATED- NT Scan Results - Concerned

I had my NT scan today at 12 weeks 2 days and the back of baby’s neck measured 3.1mm. The doctor came in and explained that this was slightly above where it should be and discussed the possibility of chromosomal abnormalities. I asked her about the bloodwork component and she got a nurse right on the phone with the lab and came back telling us that based on bloodwork and the scan, the lab gave us negative results for Down’s Syndrome and Trisomy 18. She printed out the results and ran the Cell-free DNA test but said it could take up to 2 weeks and in the meantime is sending us to a specialist. We go in tomorrow to get more info, but right now, I’m a nervous wreck. Has anyone else had a 3.1mm reading with normal bloodwork? What was the outcome?
