Thank you everyone for such a range of replies. Following the advice on here, I bought a copy of Juju Sundin's book over the weekend and have been reading it. It contains some really useful and interesting ideas and have helped take away some of the feelings about lack of control (over the pain etc).
My concerns remain with examinations - I hate the way they feel, but most of all, it is the sense of being invaded, vulnerable and humiliated that makes me so stressed. It took years to be able to go for smear tests, partly because of the treatment at my first one when I was about 19/20 - it was coarse, vulgar and psychologically difficult.
Between then and the next time I was due for one (they changed national policy so not til I was 25 or so), I had my trust severely violated by someone in that way.
I have since mustered the courage to attend two tests (both much delayed, which led to being 'told off' by various HCPs), but both were psychologically very difficult, and involved lots of tears and nightmares. Fortunately, I had sympathetic care on both of these occasions which lessened the impact.
Even with these less negative experiences, I still have concerns, especially given the heightened emotion of labour anyway and the fact that I wll not have met any of the midwives etc in advance. Yet I understand that sometimes, these are essential. I would never want to jeopardise the safety of my baby or myself as a result, however, I need to consider the pyschological aftermath of such invasive procedures.
I'm planning to write something on my birthplan to express these concerns, and will also attempt to discuss this with the nicer midwife if I get the chance.
Steakchips that's a horrendous experience, no wonder you feel as you do. Have you ever raised a complaint?
Tasmanian hi, yes I was in the moshpit for a while... I lost touch tho after ending up in hospital for emergency surgery early doors. Hope you are well!
HandMini - thank you, that's a really great idea. My DP is very much pro-authority and anti 'hippy-shit' but he does understand my issues. I think this is something he'd be able to manage and would be of enormous help given that I trust him completely.
