Most secondary applications have a section to write an essay explaining low grades, so you should be afforded that opportunity.
However, depending how you do on the DAT you will likely have to explore a post-bac or masters program. Given if you go with the traditional timeline, you will be applying this summer, meaning you only have one more semester's worth of grades, I doubt your GPA will have much movement. Try your best and ACE your classes next semester, kill your DAT, and apply early to a broad, yet thoughtful school base and you may have a shot, albeit a long one. Be prepared for the possibility of having to take a year or two off to improve that GPA.
