Painful Braxton Hicks with need to the use bathroom, normal??

39+3 and a day ago my BH have gotten quite painful (strong period like cramping and lower back pain). They aren't consistent so I'm not worried about labor but I everytime I get them I have an urge to push/use the washroom (TMI but poop). Nothing ever happens. Is this normal of Braxton Hicks or maybe it's my digestive system?
