Early Labor Starting?

BRITT - ARIAH 08/12/20🤱🏼

On the 17th, they checked my cervix and i wasn’t dilated, On the 20th, i came back due to them wanting to watch my blood pressure and i was 1 cm dilated. Now im at home, i have cramps in my back that come and go but are pretty strong. is this a sign early labor could be starting? (Currently 37 Weeks)
