diarrhea 😩😩

So I am in my third trimester as of Thursday, I usually never get diarrhea but lately it's been occurring more than usual. Upset tummy which usually I would think would be me about to throw up or be gassy. But no. Diarrhea.. anyone else??? I read it's not uncommon that it usually occurs whenever you are closer to your due date or close to labor. Which my due date is not until JANUARY . SO I'm hoping that isn't it.
