Labor?

I am 36.4 and have been contracting for about 6 hours. The pain is mostly in my lower back and hips. Initially, I couldn't come to bed because the pain was so intense but I came to bed about 2 hours ago. Still feeling pain, slept through most of it. But now I have been woken up because it is far too intense. I have never experienced back labor, is all I know is the pain is NOT going away and is keeping me up. I feel a contracrion here and there but I am constantly hurting so it is making it extremely difficult to time.
