12 weeks scan - sonographer said boy, could she be wrong?

[Twlight1]

Just as the title really, at our 12 week scan the sonographer said our baby is a boy and gave us this photo. There’s no mistaking I thought, but since looking online it suggests genitals look the same at 12 weeks?!

It's an educated guess. The nub (genitals) are similar but boys are at an angle so while she was scanning she probably got a much better shot at the nub than just a potty shot.
