Did achiness turn into labor?

Shelby
So I've been experiencing whole body achiness and mild cramping for the last 7 hours. It starts in my lower back, travels to my upper back and then circles around to my belly. It comes and goes in spurts. It feels different than the BH contractions I've been having.
Yesterday I had my membranes partially stripped, and my OB said I was 1cm and 80% effaced, and I started taking evening primrose oil.
Today I bounced on a yoga ball for an hour just for fun.
So my question is, did anyone have achiness and mold cramping that turned into real labor contractions? Or is this just my body responding to the bouncing?
