Hi it's called pubis symphysis disorder and I've had it in all three pregnancies. It is so debilitating, I feel your pain! I have tried all sorts of compression shorts, belts, Physio, chiro, hot and cold packs, and I'm sorry to say that nothing works except rest and the only cure is birth! They say to try and keep your legs together as much as possible, such as getting out of the car, putting on pants and getting in and out of bed. As for rolling over in bed, excruciating! I would cry out in pain every time! Try to remember to bring your legs together and knees drawn up before rolling over. A pillow between them can also help. Not long to go now, just rest as much as u can!
