36 weeks tomorrow

I'll be 36 weeks tomorrow, I'm very crampy, very uncomfortable. Anyone else? Could I be close to labor or has anyone had the cramps and such and went all the way to 40 weeks? I've always been small, super short, and relatively skinny. I really just feel like she is completely running out of room and it's killing both of us. :/ I guess I'd love to hear that the end is in sight. 😂
