I was tested for Strep B with my first pregnancy, mainly I think it was because my waters had already broken & they were going to let me go as long as possible to be better for our baby (I actually ended up going for another week with continual liquor leak before the decision to deliver bubs was made) . As it turns out I had it & if I had of birthed naturally they would have had the treatments all ready for me & bubs after birth ~ as it was he was born by emergency c-section so it wasn't necessary
