Is It a Hemorriod?

I have a small red bump (3/ in diametre which sticks out of my anus and is along the wall of my anus . It is the same red color as my anus and doesn't hurt-except I irritate it a little when I wipe myself after a bowel movement. It doesn't hurt at all while having a bowel movement. It appaered a week ago and doesn't appear to be getting larger.

Is this a hemorroid and should I try Prep H first?
