Girls, who had cesarean section, can tell me. Third childbirth and I was cesarean for the first time, almost a week has passed, stitches are not painful anymore, discharge is not abundant but I'm worried that I have pain in my back, like a uterus, sometimes it comes through as a cutting pain and also when I go to the toilet, I go small, it's not strong pain, it's kind of like there where the bladder is, this feeling. Is it normal? Or should I schedule an appointment with a doctor?
