I have a B.S. degree in Chemistry, would this make any difference in the requirements I would need to become a certified nurse/midwife?
The only thing that having a degree will help you with in going back to school to become a nurse/midwife would be that you will already have your basics, and will only have to complete your specialized credits if you are looking at a bachelor's degree program. As for going for a graduate level degree, that is another story. Having the bachelor's is the first step, but you will probably need to complete some prerequisites courses if you want to be qualified to apply to a graduate level nursing/midwifery program.
To get you started here is a list of online midwifery degree programs.
