Can I join you?

Hi!
I'm excited because I should know by the end of the week whether I'm accepted into the CNA training at a local nursing home. But at the interview, the lady said I was almost certainly guaranteed. It will be 2 days of classroom training and then paid working hours for however long it takes to get certified. Anyway, I'm excited because it's my foot in the door for nursing.
So I've read a few threads on here but still would like some suggestions.
As a CNA, what are the next steps to look into for further my education? Should I look into becoming a certified nurse-midwife (which is an interest of mine) and how long does that take/what is required?
Or as a CNA, can I take online classes to become an LVN? Then from LVN I know I can take online classes to become an RN? But what else? Any other options.
I'm young but I already have a family so college and lots of expense and daytime college hours aren't looking too do-able for me at this point.
Just trying to get a glimpse into the future.
But becoming a CNA is a good start, IMO. Anything I need to know before class starts?
Thanks in advance.
