Hello, have you had any postpartum bleeding? I've been having some discharge with blood for a few days, then on day two it was clear and watery, but at night there were yellow-greenish discharge with blood, like water is coming out in parts? My uterus hurts, my lower back hurts, three days ago there was a 2 finger opening, can I go now? Or should the water come in large quantities?
