13 week ultrasound gender guess

13 weeks ultrasound

Anyone had an ultrasound at 13 weeks for gender at it be wrong? Baby was really difficult during the ultrasound and spent most of it with their legs crossed. The gender determine was a boy and we even did a gender reveal. I was showing a friend the ultrasound pictures and she started making me feel some doubt about it so I decided to ask for advice with it all. It’s a boy yes?
