Need your help please! Gender confusion...

Reem

These pics are from my 12 week NT scan. Can lo have some thoughts on which gender my baby is and why US tech says she is already very sure of the gender of my baby. When I asked her how sure she was, she told me she bets everything she has that she is sure of my baby’s gender. Do you think I can trust her?? I won’t share what she said as I’m looking for unbiased opinions. I will say the scan was done at a very prestigious hospital with top of the line equipment and she did a 4d scan as well.
