most likely not though (with the c section comment) only because theyll give you medication to cure it... and once its cured its gone,but you can easily get it again id have your partner cured as well so your safe (: baby is safe though
My friend had that while being pregnant she would get medication for it and her baby was fine.
There's a possibility they will recommend you deliver cesarean so that your baby does not come into contact with it.
It is curable ... I dunno if it's harmful to the baby though but I doubt it.
