Could the ultrasound technician be wrong?

I am 20 weeks and went for my anatomy scan.

It was really hard for her to check everything of the baby since the baby’s wasn’t turning positions at all.

We tried everything like coughing, turning sides but baby still wouldn’t turn. She couldn’t even get the whole spine of the baby and gave up because it was taking forever and baby was stubborn so she said if the doc says we need the whole spine pic we’ll have to do that again , she only got the top of the spine not lower,

She also didn’t get a potty shot because of the position and because the baby wasn’t opening their legs fully.

But she said she’s pretty sure it’s a girl.

She said we’ll confirm at the growth scan at 24 weeks.

Last two times the doc said “we are pretty sure it’s a girl” it was girls.

But all three times I’ve had different docs and technicians.

What do you think?
