What Could Cause Persistent Anal Mucus, Floating Stools With Yellow Flecks, Abdominal Pain, Fatigue, And Poor Appetite?

I ve been having issues with excessive mucus from by anus for many months now, so much I feel like I almost always feel like I need to wipe, as well as a lot of mucus in the back of my throat, all the time, and digestive issues. But for a few days now, I ve also had hard, chunky stools with yellow flecks recently. I also have mild abdominal pain. Everything I find online is either about fully yellow stool (not my case, it is brown with fuzzy looking yellow spots on the outside) or mucus. However, I am unsure if it is mucus because the yellow parts are not slimy or anything, they look fuzzy or fluffy almost. My stool also floats, and since this started, I often feel the need to pass stool, but when I go to the bathroom, nothing happens, yet when I look in the bottom of the toilet bowl, there s what looks like almost sand..? Pale ish brown in color. I had a colonoscopy and endoscopy a few weeks ago but the doctor said it was normal. I m exhausted all the time and rarely hungry, I don t know what to do anymore. I am also a 25 y/o female, if that helps.
