I'm really starting to get bothered by this. I have irregular periods and am due to have PCOS tests done in a few weeks time. But the thing I have noticed (or I think I have noticed, it's entirely possible I'm just obsessing and driving myself insane) is that I seem to get symptoms of my period - bloating, the occasional cramp - at what would be the 'right' time (eg about a week before it's due) but then AF itself doesn't come. In some cases for another 3 or 4 weeks, though last time it was 'only' 2 weeks late...
If my period really did only come once every 8 weeks, I might even begin to assume there was something worng on one side only - I have heard (though this could be bollocks??) that this can happen. But as I say, it isn't always every eight weeks, sometimes it's every 6 or so.
I'm starting to get quite down about this as I desperately want my periods to regulate before we start TTC. This month I really thought AF was coming and now it hasn't.
