Diarrhea! Help!

TMI Warning! I'm currently 2 days late for AF and woke up at 1am feeling like I needed to poop really bad and my tummy was bubbling. I had a little bit of mucus come out and that was it. I woke up again around 4am, feeling the same, so I went to the bathroom and I had diarrhea.

I've had cramps on and off as if AF is coming but she is no where to be seen (hopefully she doesn't show for 9 months), tender breasts, bloating and now diarrhea.

Has anyone had this before BFP?

I was hoping to test this morning but with my frequent bathroom breaks, I wasn't able to.
