A due-date always means give or take two weeks - at three days, I would not be concerned yet - especially if the cervix is not ready. Are you using Dr Christopher's 6-week formula? If not, it might be a good time to get a hold of some - this formula helps to prepare the body for labor. You have to do all you can to prepare - then, trust your body and the baby to know when the time is right. I always recommend the 6-week formula, blue cohosh, castor oil, walking, and talking to the baby before messing with the membranes. If you are not dialated at all, then your body is not ready - relax, and give it a few more days.
