37 weeks 3 days I'm so hungry

So in the last week I've went from barely being able to eat anything at all. To eating so much! I can more than my norm and even sometimes I'm still hungry.. I'm 3 cm 50% thinned. Been having a rough 3 days with contractions, sharp pains and pressure. I've been able to sleep excellent the last 4 days except lastnight. I could not sleep for anything. I'm noticing pain in my butt. Like my butt bones, pelvic which I have SPD and the pains are in the front while I walk is when it's the worst.

SIGNS OF LABOR MAYBE? I'M SO READY, he's already 8 lbs. So tired of hurting 24/7.
