We did it twice yesterday because my doctor told us to use nipple stimulation to get regular contractions, and we cant have one without the other

but NOTHING. Yesterday I fast walked/jogged and also jumped off of a tree stump 4 times.
Im starting to have back spasms. Im hoping this is a sign of labor. Because tomorrow is my due date, and Im SO over this.
Im have a doctors appointement in the morning, and I think Im going to cry and beg them to break my water.
