I have a lot of back pain too, mostly in my really low lower back by my butt. I hope this doesnt mean Im going to have back labor!
I found it helps to either take a back and slouch down enough so that your belly is floating or to lean over onto the kitchen counter with my arms on the counter and my head on my arms and then spread my legs about shoulder width apart and just sway, and sway some more. That helps me! Try it, maybe it will help a little.
