Re: 42 weeks pregnant.
What does your doctor say about letting you go this late? Give the doctor's office a call in the morning and ask to be seen. Ask to speak to a nurse and explain how late you are and that you're concerned.
As others have said, you can be in labor without your water breaking. If you feel like the baby is ready to come because you're having contractions, go to the hospital.
If you don't have a doctor for some reason, go to the hospital and have them check you.
