I'm a carrier, too. It's all right. My doctor isn't concerned at all. Yes, they do want me to do 2 hours of antibiotics before giving birth (really awful, as I hate antibiotics). I haven't had any problems, though. I take a really good probiotic daily, so I don't get the upset tummy that antibiotics usually give me. My babies are all perfect, and I'm not worried about it, either. You probably shouldn't be, either. The fact that you know you're a carrier (and a huge percentage of the population carries GBS) means you can treat it so it doesn't affect your baby during delivery.
