I had prodomal labor. Once it started, I had it until I actually went into labor. Practice relaxing through it. It will help when you're actually IN labor. I know sleep is hard. Just try to relax and let your body do what it is supposed to be doing. Yes, it IS actually doing something. :-) That's the good part!
Try to get as much rest as possible over the next few weeks. You're going to need your energy. The one thing about prodomal labor is your body is already working. I had a very long and very hard labor and due to my prodomal labor, my body was very tired during the actual labor process. I'm not saying this will happen to you... but just be aware and try to get as much rest as possible.
Really try to practice your labor techniques while you are experiencing these prodomal labor pains.
Oh...the other thing. Since they ARE different then Braxton Hicks... meaning, they don't stop when you move or change positions.... you're going to have to keep an eye on how many you are having and if they are coming more frequently. That was the only way I knew I was actually IN labor. I went 2 hours with the contractions every 5 minutes. The prodomal labor had never been so steady for so long. An hour yes... but never 2 hours.
Good luck and congratulations on your upcoming new arrival!
