I popped a pimple of the edge of the triangle of death, it's a little red but when I popped it blood came out. Should I schedule a doctors apt?

Other symptoms? Keep it clean and put some bacitracin on it. Then, if you have pain, spreading redness or warmth, or a fever, see your doc or go to the ER. If you have no symptoms other than a slight soreness of the popped zit,if is no big deal. Getting better acne treatment is MUCH better than getting pimples, especially if you cannot resist popping them, which can increase scarring. Acne is very treatable.
