I've not got experience of it personally, but know someone who did have it during pregnancy. She didn't particularly go into much detail about it, but she ended up being induced at 36 weeks (this wasn't down to strepB though), it was because she began losing her waters at 28 weeks and her baby was very small for it's gestation.
I'm sure there's more ladies on here who can help you a great deal more then I just did!
