Noo you have them all done at your doctors, they contact you when they need you back for your next injection.
I have to wait until Monday to make the actual appointment now because the Doctors are closed this weekend and it completely slipped my mind yesterday. grr, I hope they're not all booked, if they are it says on the letter I can arrange an alternative appointment, so either way I'm getting it done

The only thing I am worried about is that if I ahve this jab on Monday... I have the dentist booked for Wednesday and if the dentist needs to doa filling, would having the jab affect what they could do?
