Anatomy Scan - Team Green

Did anyone go into an anatomy scan Team Green and accidentally have the sex revealed by the ultrasound tech?

I’m 16 weeks this week and about to schedule my anatomy scan for, I assume, 20-ish weeks, and I’m terrified that they’ll somehow reveal it even if I tell them repeatedly that I DO NOT want to know. With my son, he was NOT shy and it was very easy to find the gender at a 15 week private ultrasound and again at the anatomy scan, so I just wonder if this baby will be the same. It won’t be the end of the world, but I’d like to know if anyone has had this happen to them!
