35 weeks and 5 days a lots of painful cramps

Hi ladies, this is my second pregnancy, I'm 35 weeks and 4 days, and since last weekend, my cramps have been getting more painful, and I've been pooping more, not diahrrea though. Last Saturday my hubby and I started doing some spring cleaning all day long, I thought I overdid it so the rest of the weekend I just rested. Cramps are always there, and lightning crotch have gone more and more painful to. Sometimes I have to stop what I'm doing due to the pain, I am extremely tired since the weekend to. Is this normal at this stage? The cramps wakes me up at night. I didnt have this with my first. And also I have a c section scheduled for June 14 due to my baby being very big.
