Thanks, Blue.
You don't have to feel guilty. You do what works best for you and your family. I haven't read your story yet, but will hop over to your journal in a while to do that. That being said, whatever happened with this guy has made you uncomfortable, and this is the time in your life when you need things to go YOUR way. This is the time to be selfish.
When my DS was born, I definitely had 1 of 2 doctors I'd have rather had (no big issues, just preference). It turned out, DS was late, and the doc was on vacation. I got the other guy. No big deal for me, but if it would be for you, I say now's the time to switch!
Plus, it's great that this puts you so close to the hospital where you'd deliver.
