I'm 37 1/2 weeks pregnant according to the OB, i'm starting the labor process. of course, he said this Tuesday. its now Thursday and it hasnt progressed. Contractions arent terrible but 15-20 mins apart. Yesterday, i was sitting at work and i felt something i havent felt before. Baby girl has been sitting on my bladder for a while but when i stood up for my 900th bathroom break, a sharp pain hit the bottom of my pelvis on the left side. pain hasnt stopped, and has made walking, sitting, etc extremely difficult. Heat doesnt help, neither does ice or Tylonel. any suggestions??
