Chances of MD/DO? 3.5 GPA, 502 MCAT

My overall GPA is 3.5 and my MCAT scores were a 21 and then a 502. I'm debating whether to retake the MCAT in April or if I should apply with my current score for admission in 2017. I really don't want to retake the MCAT, so I'm open to DO admissions, but obviously prefer MD.

502 MCAT score breakdown:
Chem/Phys: 125
CARS: 126
Bio: 125
Psych: 126

Should I just suck it up and retake it or could I get a decent number of acceptances with this score if I apply as early as possible?

Any advice...
