Nervous for my appt

I have a prenatal appointment tomorrow and I’m super nervous lol..

I’ll be 36 Weeks so they’ll be doing the GBS swab! I’ve never had anyone go down there, besides my sexual partners but their face wasn’t all up in there ya know. I’m shy about how I look down there, I have “big” labias. Lol ☹️

How quick is this swab done? Should I shower before it or? Shave? lol I’m a nervous wreck..

imagine how self conscious I’m gonna be doing cervical checks and birth!!
