Submitted apps...should I check up on them?

I submitted my supplemental apps about 3 weeks ago. I've heard back from one school for an interview, but have not heard from the other two. How long should I wait before I call or email to check up on it, if at all?
What has everyone else done? Did you email, call, or just wait it out?

I just waited. From my experience, the school will send an email if they have received the supplemental apps. In my opinion, I would not call to see if you have will receive an interview invite.
