Stomach sleeping for relief in third trimester?

I’m 31 weeks. The past couple of nights, lying on my side feels like my ribs are being smashed by the baby. Seriously the only relief my back is getting is if I take my pregnancy pillow, shape it into a circle so there’s a hole for my belly and lie on my stomach. I’ve done it periodically through out the day to help curb soreness but I’m considering trying to sleep that way tonight. Anyone else do this? Is there any danger to doing that?
