Ummmmm yeah did ranked not count last night?

Just was wondering if the game I won last night actually counts , cause so far it still has not shown up in my match history and have not received LP for the win either. And I am pretty close to the bottom so if I lose two in a row I drop a division, which is not really fair considering I just won. The game before that one they sure docked me for a lose, so anyone know what's going on?
