Ultrasound gender?

Rayven

Ok so I went in for my ultrasound today, I’m about 13 weeks and 4 days. Baby was so active he/she kept moving around on the screen it was adorable! Anyways to my question. Can ultrasound tech tell the gender of the baby this early? She wrote down at the bottom left of the screen FEM when she was showing me baby. Does it mean it can be a girl? I was gonna ask but got kinda shy. (This was the pic she printed me 😁)
