Shot a Buck, little six piont.

I had him at twenty yards and had to stop him. While stopping gave him the doe bleed and got a quick reaction looking right at me. Well I shoot and he ducked the arrow making the shot high. I waited about two and a half hours and started the search. After tracking for closed to a mile a big pile of blood by the road almost six hours later. The Pile of blood and three specks of blood there was nothing. No arrow, no deer, no nothing. What do I do.
