A lot of pressure

Hey mommas so I am 33 weeks pregnant and I have been having huha pain/pressure been going on for a while but everyday it gets worse and worse, it hurts to move when I am laying down or try to toss and turn my huha hurts and I can barely turn in bed when I had my ultrasound at 30-31 weeks the lady confirmed that the baby was head down and really low, my family don't think I will make it to May 21st for my due date has anyone ever felt this way or know how I can relieve it?
