Hi, I Started Having Diarrea 7 Weeks Ago. After 3

hi, I started having diarrea 7 weeks ago. after 3 weeks I made an appt with my dr & he put me on atibiotic for 5 days 2x per day. didnt work? Ive continue to have it & im seriously concerned because its not getting better? I went to walgreens and talked to a pharmasist & he recommendd probiotics, until I told him there was mucus in my stools. after he herd that, he said I need to go see my dr asap. I would like you to tell me WHY mucus in my stools is a bad sign?
