Leah, if it is bright red and only a spot or two, it could be from a tear or irritation, especially if you have had several BMs in one day or two and if there is diarrhea or just multiple BMs that are difficult. Generally you don't need to worry unless you see a lot of bright red blood or dark red almost black blood. Those would indicate a more urgent matter. Anyway, it will not hurt to tell your physician, in any case. It may just be annoying irritation and maybe nothing to worry about, but it is always better to be safe than sorry.
