I would head of to the hospital to make sure its amniotic fluid as if it has being for a few days there is a risk of infection to you and your baby. If so you will need antibiotics and possibly labour augmented (speed up) at our hospital the policy is antibiotics 18hours after ruptured membranes if the waters have broekn to avoid infection. I'd get checked out just to make sure or at least call the hospital for some advise or the place you intend on birthing.
