I think the NHS in England and Wales are different in some ways, so I'm not sure if what I'm saying applies to England as well. But, it's a new rule in Wales that if you're examined at all, a nurse has to be present. My GP is a woman, and she still had to have a nurse present when she performed a pelvic exam on me. We both thought it was a little silly and unnecessary, but it's the law here.
Normally when getting b/c pills, or renewing a prescription for b/c, you won't be examined. When I go in, I meet with a practice nurse who takes my blood pressure and asks if I'm having a problems with the pills. That's it.
When I first came here, I just brought the packaging from my US b/c pills and the GP was able to match up by looking through whatever the UK equivalent of the PDR is. Easy peasy.
