Running support band

Kehly
Any runners have experience with support bands specifically for running? 24weeks, I feel great running, but this belly sticks straight out and my low abs are so sore after. It feels like I did an hour long ab workout, but not in a pleasant way. My back also hurts so bad that I can't roll over in bed after running. I think I need a little support. 
Any brands you recommend for running specifically?
