When should you go to the hospital if you are a couple days past your due date and you haven't seen a doctor how do you know if you are dialated or anything like that?

You should go to the doctor right away. Also, if you haven't seen a doctor during the pregnancy, you cannot be sure of your due date. Also, pay close attention to any contractions you may be feeling, and how often your baby moves within. Most important... get to the doctor!
