Is this normal?? TMI !!

I’m due Saturday & my whole pregnancy I’ve been good with my bowel movements. But tonight for some reason I’m laying down and had to go to the bathroom so I started walking down my steps and my poop started coming out all in my shorts. I tried my best to make it to the bathroom (which I did before it all came out) but it was still such a mess that I had to shower to even clean up. I’ve peed myself countless times through my pregnancy but I never had this happen. I also have a hemorrhoid so going to the bathroom isn’t always so easy for me. I’ve been having diarrhea lately but never like this. Is this normal or should I bring it up to my doctor tomorrow?
