16 week 3d scan - I'm confused! What do u think?

Hi, I had a 3d scan done at 16 weeks...US tech said oh it's def a boy, which is very clear and obvious from 1st pic, half way through it became obvious that cord is wrapped around the gender area and the leg - I asked her to double check - but all she kept on getting are clear pics of cord in the gender area...
I have attached 3 pics:
Pic 1 - looks like boy gear no doubt! :)
Pic 2 - it becomes obvious that there is a lot of cord action in the gender area which wasn't picked up on the 1st pic
Pic 3 - cord is visible and pushed to the side, I can see girl parts

Experts - what are your thoughts?
I find it absolutely fascinating that it can change so dramatically!

I'm certainly no expert and I really don't know what I'm looking at. Are you going back for a double check?

Yes! 20 week scan in 3weeks :)

I'm not an expert but I think boy still... but you're 20 week scan will give you a better indication. Be sure to update when you find out!

gender determination should not be done with 3D imaging. Good luck on your 20 week scan!
