How do you tell the difference between a Braxton Hicks Contraction and how to tell if your labor is real. A Braxton Hicks Contraction is a kind of a dress rehearsal to labor. It's your uterus priming your body for what labor will be like. So if your contractions go away, when you lie down or when you go for a walk, these are more than likely Braxton Hicks Contractions. If your contractions create a rhythmic pattern and they are not going away as you are lying down, or as you go for a walk, more than likely labor is beginning. That's the way to tell if the labor is real or if it is just a dress rehearsal.
