Postpartum discharge. Girls who had this, is it normal or not? I gave birth a month ago, the first two weeks of lochia were as usual, for the subsequent two weeks they would disappear, then reappear small discharges... I gave birth four times. After previous births, such a thing didn't happen...to see a doctor on Friday, but wanted to know if anyone had encountered this...
