Possible wrong gender ultrasounds

Brianna

I got an ultrasound at 20 weeks this past Monday for an anatomy scan and the baby was being very stubborn . They have to do a redo in 4 weeks but the tech said that she was sure it was a boy. I had a boy my first and the baby’s sex was super obvious . This one it seems like the babies penis is sort of not centered making me think it could be just the umbilical cord . What do y’all thing ? I added the picture with the word “first baby” for my first baby boys ultrasound that was actually a boy. His is centered and obviously unlike the second ultrasound.
