37+6 weeks

3 cm dilated 70% effaced and contractions every night that don't seem to make ANY progress. I don't get any sleep because the contractions keep me awake .. Usually lasting from about midnight to 2 or 3 am. I'm going crazy ! My back won't stop aching and my pelvis feels like it's being ripped apart , so walking is just painful. It's a normal pregnancy and my second ! I'm thinking about asking to be induced next week if she isn't here yet ... Would that be selfish of me ?!?
