Girls, what dates did you give birth? Did you have a cesarean or transfer? I'm already 36 weeks and sometimes my belly hurts plus diarrhea was there, now constipation. I'm afraid to give birth too early. The deadline is exactly 36 weeks, but according to ultrasound, they are full 37 weeks. I got confused?????
