Doctor or midwife?

Every since I was a young girl, I've always thought that I would use a midwife.  I didn't like the idea of medicine invading a normal process that women have been going through for many years and I thought that midwives would spend more time with the mom-to-be, both before, during, and after delivery.  I've now worked at a hospital for the past 2 1/2 years and I'm just not so sure if I think that having a doctor is such a bad idea.  Most of my friends have had complications with their deliveries and the worrier in me is somewhat nervous about having something go wrong with my delivery.  Plus, midwives aren't covered in Alberta and cost $3500 (which is a whole lot of money!).  That being said, part of me is still really drawn to getting a midwife.  I guess that I need to make a decision soon...
