Pregnancy pillow help!

Hi mummies..I'm currently 5 weeks more to my due date but recently whenever I sleep, I wake up with a very sore pain at the top of my tummy, just where the top of rib cage is. I have been using this pregnancy pillow support at both sides but it doesn't seem to work for me anymore now that my stomach is huge and heavy..I needed to change pregnancy pillow desperately, and thinking of changing to the wedge pillow..any suggestions/advice? Thanks!
