Pregnancy sex

I'm currently 6 months pregnant and I need some new sex positions that are comfortable. Doggy style hurts my ribs, and I usually like being on my stomach but that's just really uncomfortable. We use to be crazy creative and kinky but most of those I don't feel would be safe while pregnant lol also my husband says I feel "shallow" he said it's like hitting a wall while we are having sex so now it's uncomfortable for him as well...HELP :(
