Do you mean a residency contract? The match was only a couple of weeks ago as I recall so its pretty early to have contracts go out. I don't recall when we got ours but it was probably at least a month or so after the match. Call the program if you're worried.
Don't worry about it. I was told by the PD of the residency I matched in that there is a lot bureaucratic red tape a program has to go through in order to get all the necessary paperwork completed. I was told not to expect anything until at least mid-April. If I were you, I wouldn't worry just yet.
