Oh, I SO understand how you are feeling. I'm right there with you. It actually helps me feel a bit better to know I'm not the only one in this limbo (not that I wish this prodromal labor on anyone else.)
Hope it's soon for you, for me, and for anyone else who is ready!!
And, even though I am very annoyed by this stopping and starting of contractions, I totally agree with the pps. Your body is doing something real and important. And it DOES absolutely know how to labor. That is for sure!
