I've been having 21 day cycles for about 4 months now and am really fed up with it.
Seeing that my period lasts about a week once it starts, I only get two weeks 'off'. :( 
Dh has had the snip so I don't take any hormonal contraceptives and don't particularly want to start taking stuff (though would gladly have something radical done to stop periods for good!!!).
Any ideas what can cause short cycles and what can be done about it?
Thanks!
