Congratulations, K.! I had a nurse-midwife with my first. They are no different than an OB/GYN oftentimes, and that was the case with mine.
I had a OB/GYN for my second. She was super, but I really don't like being hooked up to everything.
For my third I plan on using a Midwife (not a nurse/midwife) and a birthing center. I really like the idea of water-births. (I get bad sciatica with my pregnancies. Hopefully it will help that.) If I wasn't in a condo, I would definitely be interested in home birth.
I advise visiting a midwife clinic and have them tell you about the services that they offer. There is probably more than you know. (I didn't -- even after two kids.)
There are also a lot of birthing methods that you can look into. My sis-in-law did Bradley, and that method is very interesting to me (strict diet/physical&mental exercises for coping with pain.) Basic pregnancy books often cover a small blurb about different birthing methods, but the Puget Sound has TONS of resources for pregnant women. Interview some midwives & doulas and find out what how they can enhance and support your birth experience.
Best of luck! And congrats again.
