crushed rib pains?!

I am 33 weeks and 3 days. My last checkup was April 3rd. They had told me my baby is breeched and to wait and see if he is still breeched at my next drs appointment which will be on April 18th. But I have been noticing I can't seem to get comfortable on either side when going to bed. It almost feels like my ribs are being crushed. Is this happening to any other pregnant woman? I've tried putting pillows underneath my ribs and in between my legs, nothing seems to work. Are there any solutions to help the pain or any comfortable positions to sleep?
