Unless your cramping starts coming and going, going to your back (in a regular, timeable pattern) or you get painful contractions/your water breaks, it's not necessary to go to the doctors. You can
still work, the more active you
are, the better chance you have
of dilating more, and losing more of your mucus plug & getting started with labor sooner! If your discharge becomes very bloody you should also contact L&D. Good luck!! Hopefully labor comes to both of us soon!
