I think I am having contractions every ten minutes that last one to two minutes each but I am not sure they are real.. I have been having these for about five hours now. Some of the seem to hurt but not all of them. I know that I am supposed to experience dull lower back pain and I have. I have been having what I think are contractions for the last five hours. I took a nap but they didn't go away. How do I better determine whether they are real or not. I haven't have any bloody show or anything either.
