ok this is weird asking but i am kinda scared. I did go to dr, but it is getting worse. I use to constipated?

when i went to Dr we have a schudled clonoscopy but things have changed i do plan on calling Monday but I am concerned, my stool is GREEN ( like mold green) no strong smell ( that part is normal the smell part) i have been peeing a lot it is clear, i have had a upset stomach off and on. i am no longer constipated. but i am very concerned i have not eaten anything green to cause this! it is happen close to a week. i thought it would go away it is not. this is weird talking about it but i am concerned any clues like i said i am calling dr Monday.
