Thanks everyone,

I just got back from seeing the doctor and she's booked me in for pre-natal care at the hospital, but not done any blood tests right now as apparently that isn't needed. So I'm seeing the hospital doctor in a few weeks (about week 10 of the pregnancy, I think it is), but they said nothing else is needed at the moment. This surprised me, but then I guess that if there's anything I am worried about I can always go see the GP again, and trust my body to take care of the rest of it.

GP gave me a bunch of advice about what to eat and so on, though I think I'm fairly well read up on that anyway. Otherwise, she seemed a lot more relaxed about it than I am. I guess that's understandable.
