How far into your cycle do they do it? The leaflet they gave me just says to ring on day one to book it but doesn't give any guidelines as to when it will be. Just wondering as we have a holiday booked and I don't want it to clash 
Also if I've not had af turn up by the end of the month I'm getting prescribed something to induce a bleed, how long does that usually take for af to turn up after taking it?
