Rose, I'm so sorry to hear about your friend. I'll have my fingers crossed for her that everything is fine tomorrow. I just read today a thread in the medical conditions thread, about women who have carried to term after their waters breaking early on in pregnancy. Apparently your body keeps replenishing the amnionic fluid, as long as the mother is on stick bed rest, it is possible to carry to term, but more likely just to a safe zone around 28-34 weeks. Did they tell her they will induce her, if there is a leak, and bubs is still alive?
Fingers crossed though, all works out tomorrow and she won't have to go down this road.
