Yesterday I went in for an ob appt, I am 37w2d and they told me I tested positive for Strep B. My doctor did not seem too worried, but I know that they have to start antibiotics at least 4 hours before the baby is born to minimize the risk of infection to the baby. I am terrified that I am going to go into labor and have the baby before the antibiotics can be administered. My dr said since this is my first baby that is not likely, but I am nervous. I am wondering if anyone tested positive for this and what their experience was.
