TMI 💩 💩 💩

So I've been looking as to what might cause this and nothing comes up. I have many specialists and so far nothing has really shown up in terms of diagnosis, but they know something wrong is happening inside me, causing me chronic abdominal pain (mostly consistent on my right side).

I have yet to have an actual 💩 test done (where I actually give them a sample), but I've had an endoscopy, colonoscopy, and a small bowel follow thru. Plus many CT scans and ultrasounds.

NOTHING.

I've had mucus in my stool a decent bit and of course I've told my doctor. My question is why does my 💩 come out like this. Last week it was completely pale and yesterday it was really dark and tarry, and now I've got this half and half poop.

Which - TMI - I recorded it coming out for my personal curiosity (tell me it's nasty, but I've been in pain for almost 3 years, I want to know why). I also wanted to be sure that his two-tone was coming out in "one" and not like combining some how in the toilet?

Could anybody tell me what this could mean? I woke up in more pain than I've ever been in this morning and I'm at work. My back is hunched over because if I straighten my back completely, it feels like someone is stretching my insides...

Please help, no rude comments. No I'm not pregnant, I just had an ultrasound for my gallbladder, they would've told me.
