Don't freak out too much. I was really concerned about whether I should retake my 30R MCAT (I had like a 3.9+ GPA) last December when I had no interviews. It's really dependent on when your apps went out and the individual schools. I got my first invite in late December, one around early January, and my last one (which I declined) in late March. I had a friend with a 36 MCAT and a high GPA (like 3.9+) who also didn't get interview offers until Dec. and Jan. Many of my med school classmates got invites a lot later than I did (interviewing well into April) and still got accepted. So, while you might have to reapply, I wouldn't count on it at this point. Keep your hopes up as nerve-wracking as the process is.
