Yes. I was just in L&D for several hours this past weekend with contractions 2-3 min apart but barely fingertip dilated. I've have braxton hicks 4-6 times an hour for several hours a day since 13 weeks. BUT, you always need to let your doctor know because obviously some contractions cause you to dilate, and its not worth risking preterm labor. Especially with back pain and abdominal pain, you need to call your doctor.
