If theres a little bit of bleeding from the rectum, but not in the feces, should I get it checked?

Yes. Bleeding from the rectum should always be followed up and you should ask your doctor what the next best step is. It may be something as simple as a hemorrhoid, but your doctor will want to make sure it isn't anything worse.
Too many things to. Go into here except to say this is not normal and should be evaluated by a colon rectal surgeon promptly. May just be hemorrhoids, colitis, polyps, tumors benign or malignant. I don't know your age or medical history but regardless please see a specialist sooner rather than later.
