27 year old pre med student!

Hey guys, I am a 27 year old pre med student, well I will be 28 next month. I still have a few pre med courses left to complete along with my BA and my GPA is around 3.5 at the moment. I am wondering what my chances are of getting into medical school and if I am too late to apply even if I end up applying at 30 years old. Medicine is my passion but I don’t know what my odds are of even getting in. I don’t think my BCP GPA is the best and I still have not taken my MCAT. I will definitely still pursue this career path even if I get discouraging comments but I just want to get some opinions or even success stories.
