Great news on the scans, fab pics! Here's mine at 12+5 (over 2 weeks ago now!), no idea on any of the gender guessing theories but I'm convinced boy, any guesses?
edgar they would've rung by now if you were high risk for sure, my scan and bloods were the Thursday and they said if they were high risk I would get a phone call the following Monday or Tuesday, it wouldn't take over a week. I got my low risk letter really quickly, exactly a week later, but friends in the same health board had to wait weeks! My NT was 1.9mm at 12+5 so very similar to yours.
