First time mom.. Braxton hicks or something else?

26+5 and for the last week or two I've been having some cramping a few times a day. I wouldn't call it mild but it's not painful either..? The most uncomfortable thing is that it makes me feel like I have to poop like immediately. It has sent me rushing to the bathroom at work a few times. Sometimes I can "go" but most of the time I've got nothing and this did cause some hemorrhoids last week 😖

Could this be what Braxton hicks contractions feel like for me or is my baby just pushing on my "poop chute" as my SO calls it..?
