Severe excruciating back pain

Has anyone else had/ have bad lower back pain? Mine is on my right side, lower back. It hurts when I pee, turn over in bed, sit or stand too long, walk too long. It gets worse at night no matter what I did during the day.

I’ve mentioned this to my OB, she said it’s normal and I’ve gone to labor and delivery as they thought I was in pre term labor. Everything including baby, urine, blood test is fine (thank god). But I just wonder if anyone else is in this much pain? Like it has me in tears. I’m 23 weeks pregnant tomorrow.
