I was GBS positive in my wee with DD. I spoke at length with my midwife friend about it and decided in the end that I would have the antibiotics. Reason being that as I was GBS positive and i declined antibiotics they would do a blood test at birth and if she showed signs of sepsis (certain raised numbers) they would want to take her to nnu for a course of antibiotics. The problem is that these numbers are raised just for the simple fact that she was born! As it happened I arrived at the hospital with 4 minutes to spare so didn't end up having time for antibiotics. The paed on the ward the night she was born decided to not do a blood test but she did have a blood test 14 hours later and sure enough she was showing signs of sepsis so ended up in nnu having antibiotics. It's a tough decision and it seems they try to get those antibiotics in one way or another!
