it really depends,
most of e time, its due to broken blood vessels in e anal. i.e
fresh blood when wiping.
however if e stool is tar-coloured, then have to see doc
immediately, could be bleeding from any part of e digestive tract
that coloured your stool.
give urself sometime, it shld clear, e.g one week. if it still
persists, time to face e doc. health comes first, forget bout e
embarrassment.
meanwhile, take more water n fibrous food.
