Odd belly shape

I'm 33 weeks pregnant and baby is currently bum first. 
Sometimes she gets in awkward positions and my belly turns into the weirdest belly shapes, they go very square or wonky. 
Does anyone else's belly do this? I can't figure out what body part is what and it makes me panic baby isn't growing correctly. 
Any pictures of your weird belly shapes?
