I got a very faint positive on Wednesday (11dpo), so waited and tested again on Friday and got a very clear positive. I phone the doctors the same day and asked to book an appointment for next week in the late afternoon - I can't go earlier in the day due to work. I was told that they haven't got anything available for the next 2 weeks that I can book in advance, and that I should just phone on the day to get one of the same day appointments. I don't really feel as though being pregnant requires a same day appointment, as I believe these tend to be saved for urgent cases, although the receptionist didn't make it very clear.
I have booked an appointment for just over 2 weeks time, but I don't know whether I need to see the GP any sooner? I estimate that I am just over 4 weeks at the moment.
