confusing ultrasound part 2

Okay so yesterday I posted I was confused because the ultrasound tech couldn't tell if boy or girl they said for boy they though penis but said penis for this age couldn't be that big and then baby moved again and it was gone then she said they are 90% sure it's a girl I am posting pictures what do you guys think?? Any advice helps thank you 
This is girl one baby moved and little penis looking thing disappeared 
This is boy one but tech said it was the cord and that the size is too big to be penis
