32 weeks pregnant

I'm only 32 weeks and have so much pressure and pain down there and I don't feel like it's normal . It kills me to get up after sitting down . It hurts to walk. And rolling over in bed and trying to get out of bed legit brings me to tears . I sleep on my side, drink plenty of water and try sleeping with a pillow between my legs. What is causing me this much pain ? In legit miserable and worried that it's signs or preterm labor. Help !!
