Gender at 13 weeks vs 20 weeks

Azia • Wife. Sep 18’ 💙 Nov 19’🤰🏽

Has anyone’s gender changed from 13 weeks? I did an U/S for genetic testing and we saw it was a boy. Has anyone’s gender changed from when the genitals were first seen until the 20 week scan?

here’s my scan. the lady said it was clear as day.
