boy or cord?

Went to a clinic and had an early ultrasound done. I'm 14 weeks and 5 days. The lady said it's a boy and took a few potty shots but for some reason I'm not completely convinced. She said she was SURE it wasn't the cord and even pointed out where the cord was and then pointed at what she said was the baby boy parts. If it's a little boy then why does it look like his little penis is coming from his belly? Is it just his positioning or what? Did anyone else get one done this early and it was correct or any mommies with boys and know what this may be? Help!!!
