Pain is bad

Okay so I'm getting back pain this morning. Could just be from how I sleep on the edge of the bed because my husband is a bed hog. But every time I stand up, regardless of if I'm sitting or laying down I can't stand up straight. I have so much pressure, tightness, and cramping in my lower abdomen and pelvis area. Maybe it's where her head is laying. But I'm miserable.. absolutely miserable. I don't wanna move. Even rolling over in bed is painful. Has anyone else had this? What helped with the pain. Idk how much more I can take. I got two hours of sleep last night. Maybe three and the pain on top of the lack of sleep I will be one grumpy lady today.. I wanna just lay in bed. But living with the in-laws will make the next to impossible without pissing someone off...
