GENDER HELP PLEASE?! DEFINITELY A GIRL?

Sarah β€’ First time mom, expecting Audreigh Anne July 6th πŸŽ€πŸ‘ΆπŸΌβœ¨
So I had this ultrasound yesterday, they did a 2d, 3d, and a 4d and they said that most definitely it was a girl, the only problem that worries me is that I'm 14 weeks, it was a place that guarantees gender at 13 though, is this most definitely a girl?Β
