Got "Attempting to reconnect" while in game, restarted game to fix, but it disappeared

I was playing JG Karthus (and Winning even), and we were in their base, only I got "Attempting to reconnect" and I tried to exit to come back and fix the problem. Only it didn't let me come back and it took me to the new game screen and when I checked my match history, it was like it never happened. Where did my game go? :O
