They did send me a hold letter, but I don't think you can read anything into that, good or bad. Unfortunately, we won't really know whether we had a chance at a particular school until we're holding the acceptance/rejection letter in our hands. I was put on hold at my number one school a month ago and took that to be a really good sign until I got the outright rejection letter three weeks later. So... being on hold definitely doesn't necessarily imply something favorable.
Unless you think they've misplaced your application or something, it might be good to find some way to put it out of your mind (easier said than done) until they contact you.
Best of luck.
