Hi K8, CONGRATULATIONS!! X
I am 14 weeks along and I visited my doc when I was 5 weeks after a positive pregnancy test (I only did one!), my GP didn't test me, she gave me an NHS pregnancy book and my blue notes. My midwife then called me to arrange an appt - so make sure the surgery has your up to date telephone numbers. I was 12 weeks when I had my midwife appt, but I think it depends on the availability in your area.
Whilst I was at my gp appt I had to make an appt with the nurse for my blood tests, I had that the following week. And in between the gp and midwife appt I received a letter from the hospital advising me of my 1st scan date.
Hope this helps x x
