I'm GBS+ too :( I'm going to be retested at 38.5 weeks if baby's still staying put... I'm not sure what will be recommended if test negative at that point.
I have decided to accept the antibiotics in the meantime. Since I'm allergic to several of them I am getting a less-frequently used one, I figure that's not such a bad thing. I am able to have the IV at home and it takes about 20 minutes to run through... the midwives are going to do their best to ensure I only receive one dose, and I'm starting now on all natural preventative measures that I can do to prevent yeast overgrowth after the antibiotic. Typically I don't take them, and I've never had an antibiotic-related yeast overgrowth (nor have I had trouble this pregnancy) so I hope my body chemistry continues to work in my favor. However, all that said, I am still not 100% sure what to do. My midwives don't do the hibiclens rinse but have said that if it's something I want to do and can do myself, they aren't going to fuss about it.
I had a hard time deciding with this one, but lately I've been experiencing some UTI symptoms and that sort of solidified things... I think if I was totally asymptomatic it would still be up in the air, and as I said if I test negative at 38.5 weeks... I might change my mind yet. The midwives are open to my changing my mind in labour as well. I think if I had to have the antibiotics in hospital I might refuse, just because the hospital here has some antibiotic-resistant infections going around and I would really worry about that since they'd probably just do the IV in the ER (it's a small-ish hospital) and send me back home. With (hopefully) just my own germs to contend with, I am feeling it's less of a risk at home.
Out of all the tests I've had (or refused) this one was one of the scarier ones for me. I was really, really upset when I found out (and mad because it was a vag-rectal test and I felt like there wasn't much I could do to make sure my rectum was clean, I mean, come on).
