I have it. You just have to get 4 hours worth of antibiotics before you give birth via IV.
Very common in women while pregnant. I had it with my first and one my I went in to labor I had to go to the hospital to get the antibiotics.
I tested positive for it as well. I have been told that as long as I get the antibiotics as soon as I go into labor it's nothing to worry about. It can pose a threat to the baby if you don't get the antibiotics but it's actually very common in women. Just make sure as soon as you get to the hospital you are adamant about getting the IV as soon as you get there.
