I think infection has to be from your blood? Could be wrong, can't remember... but I refused the test and also AB's in labour which is "protocol" if you don't test cos they assume you to be positive. They did say that as long as bub didn't get a temp within 24 hours he was fine... so I went with that and they did 4 hourly obs on him overnight and I went home the next afternoon I don't think you're crazy, but seeing as you know you're positive at the moment (doesn't mean you will be at time of birthing by the way) then if there seems to be a BIG possible risk at the time of birth for bub to get infected then I'd be doing what you're doing
