Hip pain?

Any of you mamas experiencing hip pain throughout the night? I fall asleep on my left side, wake up to pee with severe hip pain, so I go back to sleep on my right side, wake up to pee, same thing. It goes on like this all night. I sleep with a pillow in between my legs and still have pain. I'll be 36 weeks in just a few days so I don't want to go buy a new mattress or anything, just wondering if anyone has experienced this and what worked for you?
