Pubic bone pain.

I'm currently 24 weeks. Every day all day I have pubic bone pain/discomfort. Sleeping on my side is not an option because that seems to make it worse. I'm most comfortable laying on my back with a couple pillows and something under my knees (I sleep with an ice pack between my legs some nights too). Lifting my leg to put pants on and get in a vehicle is even uncomfortable :(. Any suggestions on stretches or something else that might help is welcome!
