Ultrasound at 17 weeks help?

Angelinaaa

I’m very confused at this. The entire time the tech said the baby had it’s legs crossed and said it’s a girly position so she went off that and passed it as a girl despite never seeing or at least pointing out the genitalia of my baby. I literally have no clue what I’m looking at because she never explained lol ? Help ?? Heart Beat was 145 I believe. If that helps 😞
