Michel Odent covered that topic when I did a course with him. He said that the evidence of doing nothing up to 72 hrs after SROM, where the mum is asymptomatic, has been shown to have the same outcomes as giving IV abs. After that time there hasn't been any studies. You have to think about what the consequences for you and your baby are for both having IV abs and for not. In the UK and other countries they don't test women for group B strep.. I think it is an individual decision for each woman. But for me I wouldn't unless their were symptoms of infection. I would want the baby to be colonised by the bacteria of my body when it is born to imporve it's health for the rest of it's life
