It all sounds very frustrating and miserable and I relate. I went through this same thing with my first and second child. However, if the contractions are stopping or letting up, you are probably not in active labor. The real labor pains don't go away. You may be in early stages of labor and your body is gearing up for it. Is this your first baby and how far along are you? Either way, I'd say just wait and see what happens over the next couple of hours. If the contractions get regular or unbearable, get checked out. But otherwise, see how you feel in the morning. Best of luck to you and congrats!
