TMI warning question

Those of you who have had your babies already (yes I know some of you will say it’s different for everyone ) , this is my second baby , how many of you had diarrhea as a symptom of preterm labor ? I’ve been having Braxton Hicks for weeks and was in L&D last Monday for real contractions. I have had the runs all day today and for the past three days a horrible migraine (it finally went away this morning 🙄) does it sound like preterm labor ? Or some bug ? I’ve had pressure in my hoohaw for days as well and my legs feel like I can barely walk. I’m 35 weeks tomorrow. Anything helps.
