GBS test??

Okay I don’t know why but this is stressing me out!! I’d like to hang on to my dignity for as long as possible before going into labor in a few weeks when I know that will all go out the window.🤣 how is the test administered?? Do they swab inside your bum? And do they use the speculum for the vaginal swab?? I hate that stupid contraption so so much!! My husband will be with me but I’m tempted to leave him in the car!! I feel like I’m going to come walking out of there like a dog who just got his temperature taken!
