I've been keeping a note of the length of my cycle since the beginning of the year, I'm not trying to get pg (an 8 month old is enough to put me off any more for the moment anyway!).
The thing is it is completely erratic. So far it has ranged from 24 days to 36 and still counting (I even bought a pg test today - not that I think I'm likely to be but just to put my mind at rest!)
Is this even vaguely normal?
