TESTED POSITIVE for Group B Stro

Hi All,
I will be 36 weeks tomorrow and I just received my results that I tested positive for Group B Strep. I'm super terrified and nervous!!! Has anyone ever tested positive for this? My doctor said they would give me antibiotics when it was time for labor. I can't stop crying though. My pregnancy so far has been going pretty good so far. I guess I'm super scared because I miscarried last year around this time. PLEASE HELP!!!
