15 week gender ultrasound??

Brooke

So i called to schedule for the gender ultrasound and the rep lady went to 15 weeks which is Jan 27. Im due july 16 2022. Has anyone had good luck on finding the gender at 15 weeks or is that too early, shouldnt the gal know that? But i took the appt, anxious but curious if able to or not?! Thankss!!!
