In brief: Nose bleed
The most common reason would be a nose bleed causing blood to be swallowed.
One needs to be concerned about a foreign body which may have been inhaled. There are a number of rare congenital abnormalities or lung problems that would entail a full pulmonary work-up but these are extremely unusual.
