Girls, who had a planned Cesarean section? How was it? I just didn't understand anything. They told me to come on the 13th with things and they would give me directions for surgery. So that means they will operate on me on the 13th? Or will it take several days? How is this even supposed to work? What should I bring with me then? I thought I would go by contractions and again, nothing was said about it ? Help?
