What is the likelihood that my newborn could contract group b strep after the administration of antibiotics?

Please ask your OB!!: As since u are beta strep + your OB should have discussed this with u since it is common to be beta strep + as i always discuss this with all of my + beta strep pts if u get antibiotics the chance is very low, not zero but very low your baby will get it and your baby will be watched in the nursery for any possible signs and if u get srom and no labor it is impor to call your OB right away.
