I was doing shared care until about 15 weeks or so. I wasn't impressed cos I spent most of the appointments with a midwife and the GP came in for about 2 seconds - she was really nice, but I made up my mind then to go straight to the midwives through the birth centre, seeing as the GP couldn't tell me general things I didnt' already know!
I'm really happy with the midwives now and they are delighted that I have read as much as I have and how much I'm looking forward to the birth
