So many things to think of, confusedog.
I want to share with you that I have considered Med school too.
As an aspiring NM, the competing option for me would be Family Medicine and a residency that is OB heavy (I didn't really feel attracted to an OB residency which is just so surgically-minded) but these are hard to find except in the Midwest. Ultimately the difference for me would have been the ability to conduct complicated deliveries (instrumental and c/s) as opposed to low risk deliveries and being a surgical first assist at c/s when needed (which I think is amazing for continuity of care, how cool to not have to "abandon" patients when complications arise).
Ultimately my goal is to reach the majority of low risk women (and keep patients as low risk as possible when they are higher risk and co-managed with an OB) and offer them as many respectful options as possible. The scope of practice for a NM is so wide that I can do homebirths or co-manage higher risk women if needed, and that will be it given where I am in life, but sometimes I think if I had been younger (in my 20ies) and American (with access to fin help that green card holders can't access sadly), I might have gone the OB way within a Family Medicine framework. So I hear you!
Do you have all your prereqs? If you do, that might be an option. I have a friend who is a physician, she initially completed her prereqs thinking she'd go the PA way but ended up applying to MS instead.
The cost of studies in the US is truly sobering.(end of my rant:))
