I considered BSN + CNM a couple of years ago.
Only this year did I find out that the job market for CNMs is pretty saturated, at least where I live (big city). The director of one local midwifery program told us she gets a ton of applications for each open position; there are more CNMs graduating than there are jobs. This is partly because CNMs really like their work and tend to stay in it for a long time, and partly because hospital programs are having trouble attracting clients (often because of insurance issues).
So, before spending a ton of money and time on this career option, I would definitely look into your local job market, and consider how far you'd be willing to move if necessary, and how long you could cover your debt if you had to wait to get a job.
I chose med school instead, in part because a very good friend (RN for 20 years) told me I'd last about 5 minutes as a nurse. 😀
