Did I play a new position?

I have played some opening in a game and then it wrote to me something like: in database there are no posistions like this

Did I just play something so bad, it was not recorded before? Or is the machine broken? I want to name my new opening! XD

Show the game so we can see it for ourselves.

Basically the game said to me that the move: Knight on c6, was never played before in this position

There are some games here.

Of course no GM games.  

Black's move d5 and then d4 is very unusual of course. Nc6 is not bad.

So basically it was not played on Chess.com, but still it was played. But since it was not played in any GM games, it is not named. right?

Well, different sites have different databases. I am sure chess.com have many master games in their database, not only gm-s, but this is an odd position, Nimzo Larsen in combination with black playing d5, then d4 (moving the same pawn twice in a row). That can surely eliminate most of the master games.
