I'm in shock?

I'm in shock? I had an ultrasound today with an inexperienced doctor, by the way. She didn't say much at all. She smeared gel on my belly for 15 minutes straight, I wiped it off, you can see she's young. The due date is 27-28 weeks, she didn't even look at the baby. I asked about the sex, could there be an error? She says yes, there are errors, 50/50. But here, your legs are bent like a cross and what??? She took a decent sum of money for these stupid words! ? It was at a paid clinic. Now I'm thinking that they definitely said the sex,
