My first 3 pregnancies I never even got tested. I had done the research and knew that even if it was positive, that I would refuse antibiotics. My last pregnancy I was .... highly encouraged......to test because she was a new practice and wan't to cya in case of transfer. I very begrudgingly did the test myself in my own bathroom. It was shockingly positive. Even after doing her prevention protocal of lots of garlic, probiotics, vitamin c, (all orally) etc. I REFUSE to test trick. That could be dangerous if the baby is born sick and they think you were gbs - and don't properly treat the baby. But anyway, since my one test was positive, it's highly possible I was positive with all of my babies. None of them were sick. We didn't do anything special in birth. We didn't treat them because they weren't sick, I did NOT do antibiotics in labor. And in fact, my midwife that pushed me to test, even told me that your water breaking, essentially does the exact same thing as a hibicleanse in that it "washes" the birth canal. Except your water breaking is more natural and no negative consequences of messing with the good flora too. At my 2 week follow up, she apologized for pushing me to test in the first place and said that she caused stress on me and our relationship by pretty much making me doing even though I already knew how I felt about it and how I would handle the situation regardless of the outcome of the test. That she's having second thoughts about how she will handle this testing in future and that she was sorry to have put me in that position.
Even though she really pushed for it last time, she presented the options of "treatment" and then respected my decision to not treat at all. Just because you are gbs +, doesn't mean the baby WILL be sick. It's a VERY small percentage that do. And those that do usually respond better to antibiotics after birth and less antibiotic resistence than those that received treatment during labor.
