I've had loose stools with mucus and clear mucus on its own come out of anus for a week shall I see a doctor?

Go see your doctor. Any time symptoms persist, it's always a good idea to check in w/your family doctor (or gp on your side of the pond). Loose stools or diarrhea is more worrisome when accompanied by stomach pain, blood, fever, sweats, chills, etc. Think back to where you last ate before getting sick. Ask your mates if anyone else is feeling poorly. Some anti-diarrhea medications may be available w/o prescription.
