Ive had bright red bleeding with every bm for months. im noticing the passage of blood clots as well. what could this be? can hems cause this?

See doctor soon: You need to be seen to find out the source of bleeding It can be growth or vascular malformation-etc Hems do not cause bleeding.

Depends: Bright red blood usually comes from tissue injury near the outlet. That might include a scratch in the outlet, hemorrhoids, etc. A darker blood suggests it comes from higher up & undergoes some change. Since the causes vary from simple/minor to nasty/bad you should go in to have it evaluated.
