The M-word

Remember how some weeks ago I whined about my cycle being three weeks instead of the four weeks it had been for years? Well, apparently the body took my complaint very seriously, because this month it's been five weeks and I'm still waiting for my period. Should I be worried?
( As if that wasn't enough TMI, more behind the cut... )
