Weird poop?

Yes I'm aware Glow users are not medical professionals. However I've always been a bit of a hypochondriac and over dramatic when it comes to my health, so I need second opinions so that I know I'm not freaking out for no reason (or vice versa).

So for the past like...I'm not even sure how many months, probably 6 or 7. I've been having weird uh...bowel movements? For the first few months my poop was either green, or super dark (not black though), or mixed of both. Then this past month I've head diarrhea for a month straight almost (probably about 3 or 2 and a half weeks) but I wasn't dehydrated, feverish, or nauseous during that, I felt perfectly fine and the diarrhea was normal color. Anyways, so the last two days, my poops gotten solid again, however it's a super light, yellow-tan color. And I've been feeling nauseous and so so so fatigued on and off the past week.

Googling this, I couldn't find anything with all these symptoms together. But from what I did find, WEBMD pretty much has diagnosed me with cancer, or gallbladder /liver problems. I'm only 18, and I don't smoke cigs or drink alcohol hardly. Theres no history of cancers or liver/gallbladder problems in my family either.

Should I just ignore it or go to urgent care/my doctor?

(Also anonymous cause talk about my poop is embarrassing 🤦🏻‍♀️)
