Congrats! I would definitely wait, just be sure you still have a positive once AF is missed. Also, I had a GP appointment 3 days after AF was due and my positive was the day AF was due. Even though I went that early (wasn't actually expecting to get an appointment that quick- next day after I rang), I didn't hear anything from the hospital until I was 8 weeks, so a month after my GP appointment. All the GP did was give me an estimated due date based on LMP, went over things to stay healthy for you and baby and asked which hospital I wanted to be referred to.
Again, congrats!
