Ah thank you all,
It is reassuring to know it's not just me that worries about this.
In terms of private, the one I've been looking at is with Spire and the 2 consultants are based at the local hospital so NHS as well. So I would hope that they wouldn't just use it as an option for further tests but I do take the point.
Home cervical screening I just couldn't, I'm sure I'd end up doing myself a nasty injury.
Thanks for the advice I will take a list of questions to the GP and keep you all posted.
