Secont pregnancy cramps

Today I am 16+1 with our second baby girl, Emily Claire! With our first, Olivia, I had a C-section because I had high BP, was past my due date, and my body just wasn't doing what it was supposed even after 24 hours of trying to induce. The past few days I have had really bad cramps and it hurts to get up off the floor and sometimes sitting different ways. I thought it was because I was a little dehydrated but I have been drinking tons of water and no changes. Anyone else have this issue with second pregnancy after a C-section?
