Welcome to GMAT Club!
Your MBA goals are very similar to quite a few folks - those trying to break through the glass ceiling to the mid and upper management and those who are stuck in a dead end job or industry. You do have a bit of a unique profile based on what you have outlined and many schools like that.
Based on your description, it seems a tough time to be going for an MBA while you are the sole bread-winner and supporting your husband. He won't be making much when he goes into residency either, so you probably have about 4-5 more years of you supporting the family. So your thinking is that you will not have the time/opportunity to quit your job, which is probably right thinking - will be tough to make it on just his pay during those initial years.
There is also a question around children. My wife wanted kids before she turned 30 for health reasons and I think it was the right call - you may have different plans and obviously people are having kids much later in their life but something to consider as it will be smarter to get an MBA before you are heading back into the workforce (if you do that) vs. doing it before you leave it.
There is a bit of a discussion/concern with getting a low-ranked MBA degree and while it helps with the personal satisfaction and self esteem, it may not help in other areas such as recruiting in Bay Area or New York or scoring a cool internship that you need to beef up your resume. My concern is that while an MBA is a rewarding and enriching experience, it may be a lot of work without a clear next step, esp if you go to a low-ranked program like UAH. MBA@ UNC is much more interesting and challenging to get into but it is worth the effort. Alternatively, if you are going to move to CA for example or New York or Colorado, your UAH network won't be very helpful and if you are going to go to a small local school, may as well go to the one in CA, NY, or Colorado, where it does have a known name and a bit of a sphere of influence (if you can't go to a national brand name school).
My suggestion would be perhaps to keep your ear to the ground and perhaps consider doing the pre-work for the MBA (take the GMAT, figure out your career track, recommendations, etc) in time for your husband's residency placement and pull the trigger as you know it (if MBA is still the right move at that stage in your life).
Good job planning and thinking ahead!
