I have one of the wedge piollows like Roryrory has - I love it too. I found with a pillow underneath my belly I didn't have a slope for my belly to rest on - I kinda had to haul the belly on to the pillow. Doesn't make sense but it wasn't comfortable!!! Anyway the wedge was my saviour! I love it! I brought it from a baby shop here in Auckland but try the big baby shops near you for one.

I also have a pillow under my feet as well as I find it helps the swelling.

I didn't get the wedge pillow till about 2 weeks ago as I didn't find I really needed it until then.
