This is probably the best way to go, it shows med schools that you have analytical skills, no one wants a person that just does biology because all they know is biology and there is so much more than just science in medicine. There is ethical, analytical and critical thinking skills that goes into medicine. I think this is the best thing you've done. Remember to take all your pre-reqs. This goes for most careers, they don't want to know that all you know is that field, you have to put something else to the table.
