Crampy and pooping.

This might be TMI. But when I woke up at 11, I stayed on the toilet until 11:30 pooping. Very light cramping. Now at 12, I'm back on the toilet and have been for 10 minutes cramping and pooping. I'm 37 weeks today and I was dilated to a 1 (2 weeks ago) haven't been checked since. Is this normal? I'm also scheduled for a c-section in two weeks.
