28 week scan gender reveal

Aree

Hello

Wondering how obvious the gender is at a 28 week ultrasound. We don’t know the gender of our baby but today my sonographer was zipping around and said to me “do you know the gender?” I said “no, we aren’t finding out. But do you?” And she said yes. And I said “wow that quickly? It must be a boy then if it’s that obvious”.

My question is, is a girl super obvious from a quick glance at 28 weeks gestation too? Or do you think this indicates we are having a boy?
