AF is one measely day late, and I am trying not to get over-excited and trying to avoid testing for at least another few days. My cycle is normally a very very regular 28 days, and I can't remember being late before, but I am well aware that I wasn't quite so desperately counting the days before! I know of friends who have been 4 or 5 days late before (on regular cycles). How long do you think before I could start to get my hopes up? a week? 10 days? Would be interested in hearing other people's tales, thanks.
