It depends on what you ate beforehand. That is, if you ate something that was primarily red (cake, cookies, fruit, cereal, etc.) it could make your "you know what" red. This could occur up to three days after you ate that particular food. But, if you dd not eat anything red and it looks like blood, then that could be bad. Sometimes, foods such as popcorn can cut certain areas in the body which could cause blood to show up. If it continues for more than two days, I would go to the doctor.
