I had tested positive for Group Strep B and had my son naturally. Just make sure to get to the hospital as soon as you start going into labor, so you have enough time to get the two doses of the medication. I was induced so I soon as they started my medication for my induction they also started the medication for my Group Strep B.
Also it is very common and can go away at any time. My cousin was positive with the birth of one of her children and a year later with her next child she was negative. I hope this helps!!!! ^_^
