Doulas, midwifes and waterbirths

Hi ladies,

I'm 17 weeks pregant with my first child and T1 since age 13. So far so good with the BS control since i'm on the paradigm CGM and pump. I also have ITP which is also stable at a good level right now and monitored constantly. 

I'm looking into alternatives to giving birth in a hospital with my OB. Mainly, I don't want the clinical feel and prefer the idea of natural childbirth, or as close as i can get given my high risk status.

Does anyone have experience using a midwife or doula? Has anyone had a waterbirth? I'm very interested in it but have read concerns for mothers with gestational diabetes. I'd love to hear about your experiences.
