Accurate sexing scan?

Would love some thoughts on these scan pictures.

We had a private early sexing scan almost 4 weeks ago when I was 16+5. Told boy (pictures below).

Today I had my routine 20 week scan and asked to confirm the sex. Straight away was told girl. I said I’d been told boy just a few weeks ago to which the sonographer replied “yes probably is a boy” and blamed the position of baby. I agree he/she was being difficult throughout the entire scan.

Although I would be delighted with either, it’s given me a little doubt and would love to know thoughts on the sex.

Surely these are boy parts I’m seeing?
