Cat may have eaten glass?

Recently my cat knocked a glass off a table and it broke. Later, when it was playing with me, it play bit me and i noticed there was some small amount of blood coming from its mouth. I guessed this was probably related to the glass breaking, and worried that the cat might have even a peice of glass or something. The cat still acts energetic and all. Is this something I should be very worried about? if the cat did eat some small peice of glass, would it probably just pass it succesfully?
