Ultrasound says boy but possible cord?

Ky

I went for an ultrasound at 13+3

the tech said boy. I felt off about the results and after going over the ultrasound video we found that one of the potty shots is most definitely the cord as you can see it pumping in the video then watch her freeze it then write boy 🤦🏻‍♀️ now I do have one shot that makes me think it is a boy but I would love to hear some other opinions.
