Anyone else's labor start out with contractions lasting 1-2 minutes and happening about every 1-2 minutes? They just started within the hour and aren't very painful. My lower back simultaneously started hurting as well. I was having what I thought were BH contractions every 15-20 minutes the last 24 hours but they would stop and start up again at times. Not sure if I should wait til these contractions become way more painful or if I should call because they are happening so quickly, one after the other. TIA!
