Blood on toilet paper after bowel movement, should i be worried?

See GI doctor: The bleeding may be from anal disease (e.g. Hemorrhoids), but you need a physical exam and a more thorough history as well family history to make sure it's not something more serious. The best thing to do is see a GI doctor.

See details: It may just be related to a hemorrhoid but any rectal bleeding should be evaluated by a doctor.
