Gender at 21wks

Okay so, I'm just a tiny bit jealous of all these ladies finding out the gender so early! My doctors office doesn't do the scan until 21-24 weeks. I have to wait another month 😐 the good news is, I'll be finding out days before Christmas and my birthday is the day after Christmas...I'm just going to consider it an early Christmas/birthday present 😍 is anyone else having to wait so long?
