Tmi! Help!!!

I've had diarrhea for the past two weeks. I read here on <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a> that it's signs of your body getting ready for labor. Is this true? I've also been getting Braxton hicks for like the past 3-4 days. How can I solid up my poop lol. By the way I'm 37weeks tomorrow
