have I ruined my chances?

<p>I recently found a letter from Tufts that had gotten lost amid stacks of my dad's mail.. it confirmed that they had received my application and advised that I notify my local chairperson (they provided a phone number) if I wasn't contacted for an interview within 3 weeks. the letter was dated 1/27 so needless to say, 3 weeks came and went with no interview. What should I do? I visited twice and spent last summer in Boston, and my supp essays are very well thought out, but will this make them think I'm not really interested? nothing could be farther from the truth.. I'm considering emailing them but will they think I'm making excuses? or worse, is it too late? any advice would be greatly appreciated.. thanks so much</p>

<p>i wouldnt worry about it.</p>
