Group B strep

El
I had my test done last week what exactly is this done for? If I test positive what does that mean? If I test negative is that good, well I know it is good anything that comes back negative is good besides a pregnancy test ha ha I did look it up on mine but it really doesn't say much so I wanted to get another woman's perspective on what does it mean to test positive is it bad? I'm still waiting on my lab results I will be giving them tomorrow when I go to my Doctor's appointment
