Ugh! Anyone else experience this?

Amanda • Soon to be a momma of 2! Excited for another baby! Wish love to you all!
This is my second and I'm due on Monday. 
I have had increasing pelvic pain for the last 3 days and usually it'll go away after I walk a few steps but now it continuos, I can't shake it off. 
Doctor says to, even though it's painful, to walk and move because that's the baby laying so low and ne moving will open up my cervix. 
I never had this with my first and it sucks! 
Anyone experience this and go into labor soon after cause this momma is doooooooooooone. 😩
