Currently enrolled at a cc, what classes should i take if i want to be a doctor but transfer ASAP to a UC?

im currently enrolled at my local cc and hope to work in the medical field someday, specifically as an obgyn. I just graduated from high school and all i feel at this moment is great regret for not trying to do my best academically and for not applying to many CS's and no UC's ( didn't think i had a chance for UC). I did get into a few cal states but opted not to go as I was told it was easier to transfer from a community college to a UC. As of now im stuck at a cc, which so far sucks because I haven't been able to get ANY of my core classes. Since I'm completely new to all this and no one in my family or group of friends is familiar with all this current college stuff, I need someone to give me some helpful advice from their experience. I'm very confused as to how the whole becoming a doctor process works in my situation. What classes should i take at my cc and how and when would i be able to transfer? If i do transfer what classes am i suppose to take at the cs or uc i go into? then theres med school? I apologize for asking so many questions that may or may not be obvious but i really need advice at the moment so thank you for your consideration :)
