What can I expect for the strep test at 36 week appt

I’m 34 weeks and kind of nervous for the strep test. What is it like ?? Does it actually have to go inside your butt 😑😑 is it weird to bring my husband for this ? He comes to all my appts. I’m so worried about them saying something about me not shaving or having a lot of discharge right now I’m embarrassed and so insecure righr now.
