Probably right, but: if it continues, you should be examined to make sure it is nothing more. If you feel a lump or swollen or tender area at (or right inside of) your anus that goes down when the bleeding stops, it is more likely to be a hemorrhoid. If there is no pain or swelling, or if you have abdominal pain or cramping or change in your stool consistency, or continued bleeding, I would get seen sooner.
