Med schools don't care about your major, though privately I think you're more likely to stand out among all of us bio-major types. Graduating early is also a nonissue so long as your application reflects maturity, good decision making and time management, and you have the same ECs as those who had an extra year to acquire them. Your clinical experience really stands out. Since you don't have research, you'll want to shine in another area as well, like community service or leadership.
