Clear yellowish gel can also be fresh bile, it has no odour. (A doctor told me this and I have passed it). Toxic bile is dark green and foul smelling (A doctor told me this too, and I have passed this too!).
But it does sound to me like you need to see a doctor and find out what is going on. Rectal bleeding is not to be taken lightly. Get the diagnosis first, then assess all your options, then make your healing path decision.
