So- I'm 40 weeks pregnant, due tomorrow. I havent really had true contractions but I feel a TREMENDOUS amount of pressure in my pelvis and lower back. Will I know when Im in labor? Im in a lot of pain but really it isnt contractions. I know I may seem weak.. but Im terrified of not making it to the hospital in time for an epidural. I dont want to miss the signs. Any advice, welcome. I go back to the doctor on Wednesday.. should I just wait until then for answers?
