Thanks for the feedback ladies!
Sorka - GBS comes and goes throughout your life. I was also tested (by accident -student practitioner.) in early pregnancy (neg result) but the test was useless, because it may come and go at any time. They want to know what's happening right around the time of labour.
Standard practice here is to administer IV antibiotics in labour to anyone who has tested positive. They don't do douching or anything else. Home birth would definitely be out. And with 15-40% of women testing postive, I don't know if I want to take the test and lose that opportunity unnecessarily. It seems to me that my baby would be more at risk if I fell into a "high-risk" category. (as in my first post.) Then I would definitely seek treatment for me and baby.
I welcome the feedback - love to hear more opinions! Thanks!
