Gender prediction kits vs. your intuition

Has anyone done a gender prediction thing (gender pros, gender experts, or sneak peek) and received a result that isn’t what your intuition thought?

I’ve tried gender pros (6w ultrasound)and gender experts (9w ultrasound) and got boy! HOWEVER my gut just tells me it’s a girl. It’s my first baby so I have no reason to favor one, I would also like a large family of each!

Am I just missing something in these ultrasounds that scream boy??? I really don’t see how they figure where the placenta will be.

I should also note I have a hematoma and I feel like that might be the “predicted placenta” they see
