I'm 12+2 today as well and I had my scan this morning. Was first time seeing baby on scan and had a nice strong hb. Tech said NT measurement was good. I got the Verifi test and have to wait a week for those results, but feeling positive based on the scan today....and I'm measuring 4 days ahead. Good luck to you on your scan!
P.S., this is #3 for me and our last.
