Persistent painful Braxton Hicks contractions

Hi all, wanted to ask if anyone here experienced painful and rather intense BH contractions (tightening of belly, lower pelvic/ cervix pain, back ache) for long duration? Is it normal? I'm currently at Week 38 and been having it for 10-hours straight for 2 nights, with each pain lasting 30-60 sec and consistent 10 mins interval but doc say it's not real contractions. Any idea will it last more than a few days? Any advice or sharing is appreciated!
