I didnt see one at all. My gp organised all the blood tests and then I had an independent midwife from 14 weeks (which isn't cheap but so worth it...I got 6 weeks worth of after care also and she was an LC so helped with all the breastfeeding stuff too).

You should be able to do shared care with your gp to keep costs down.

Have you considered a homebirth or midwife lead birth? (I ask with trepidation in case you think I am a homebirthing evangelical)
