Anyone ever get re-tested for Group B Strep closer to delivery?

Yesterday I was 36w,5d and had my Group B test. It came back positive. I have read that sometimes it can come and go, and I really would prefer not to be strapped to an IV pole during labor if it is not necessary, so I am planning to ask them if they might be willing to retest me in a couple of weeks.

I already asked about the possibility of oral antibiotics, and they declined.

Has anyone ever had a second test to confirm?
