Freaking out over a common app mistake. Should I contact admissions?

I forgot to put on my common app that I interviewed with BMC. Will the interview mean nothing now as it is undocumented?

How is it “undocumented”? Also, did you visit or show interest in other ways?

I did visit in December. I’m just scared that maybe my interview won’t “count” bc I never formally said I did an interview with them.

You do know that most (all?) interviewers have to make a report and send it to the school, right? And that’s the point of the interview?
