Probably too late to submit an AMCAS right?

I scored a 499 (124/123/124/128) August 1st and then I received my new scores yesterday of a 512 (126/130/126/130). I got 2 interviews with the 499 for DO schools already. I thought I would not get anything close enough for MD so I never completed an AMCAS. My gpa is not impressive though: cGPA: 3.51 and sGPA: 3.298 (or probably 3.3 with AMCAS). ECs include chorus, biomedical (breast cancer) research, patient companion volunteering, receptionist/clinical assistant (not MA/CNA),... Probably too late to submit an AMCAS right?
