I do know that 50% of pregnant woman have GBS. And they would have never even have known before they were pregnant. It doesn’t do anything to us but can be potentially dangerous to the baby. But what they will do is give you antibiotics when you go to the hospital and are in labor. You will receive lots of antibiotics through an IV and it will more times than not clear up the GBS infection. A lot of woman are diagnosed with it, and it usually never causes anything to happen to the baby. The only way that it would cause anything to happen to the baby was if it wasn’t treated before the baby went through the birth canal. And if the infection does not clear up by the time you have to push, they will probably give you a C-section. Just trust your doctors they know what they are doing, and I am sure your baby will be a very healthy one!! Good luck , and just let us know when your baby is born how everything went!! I will be praying for you.
