I'm wondering if anyone here started their pregnancy with an OB, but then switched to a midwife at some point. If you did this, when did you switch? This is my first pregnancy, and I want to have as natural a birth as possible. I currently have my first pregnancy appt with my OB scheduled just before the 10 week mark. The appt includes an ultrasound, and if everything appears to be going okay, I was thinking about switching to a midwife after that. Does this sound like a good idea?
