Hello, Uhmm So I Have Been Going Through A Really

Hello, uhmm so I have been going through a really weird disease for the past two months. I don't know what it exactly is but whenever I spit there is an orange/greenish fluid in my saliva and specially in the morning. And sometimes when I spit really hard I get to see dark orange bits, I continuously saw them so I decided to smell it and it smelled really bad and was causing a bad throat smell as well. So please if you could at least tell me what the disease I m facing is that would be really great. (Hopefully nothing bad :/)
