Call your doctor. At this point in your pregnancy, you should have the phone number memorized. Ask the doctor your questions.

It very well could be the start of labor. As a L&D nurse I would recommend you call the hospital where you are scheduled to be delivered and see what they recommend. If you came in to my unit tonight, I would augment your labor.
