...stick a clove of garlic up your fanjo?
I have heard about it for thrush but I've never heard of it for GBS.
I'm 30 weeks pregnant and have had positive GBS results every time I've been tested for the last 7 years, so assuming that I'm positive. I'm having swabs done at 34 or 36 weeks (can't remmember which). But I'd love to avoid having antibiotics during labour.
