Anyone else having start-and-stop contractions for days on end? This is my third, and I know what real labor contractions feel like-- especially the back labor ones. These *feel* so much like the real thing, but then they stop after three or four hours. It's been happening since last weekend! What's the deal? Is this normal, or is it an indication that I may need help for this labor to progress? Trying to avoid medical intervention this time, as I successfully did last time, but I'm getting worried. Both my other children were born by now! Ideas or advice? Anyone in the same boat?
