Labor signs?

Moms this is my second baby but I can’t seem to remember how it was with my first. I’m almost 38 weeks pregnant and can’t seem to stop pooping. It’s normal stools not like diarrhea or anything like that but its only 11 in the morning and I’ve gone 3 times and only had breakfast. I’ve been going twice every night as well for the last 3 nights. I’ve gone so much my rear is in pain lol
