Kim ~ i would say if your right about having 21 day to your cycle AF will most likey rear her ugly mug but in saying that i may be completely full of crap i think it is well and truly impotant to chart from CD 1 through it will give you a much clearer idea whats happening are you still feeding Darcy? i wonder if the hormones attached to B/feeding contribute to the shorter cycles ?? i remember my ivf doctor saying that if you have a luteal phase that was any shorter then 14 days it would be very difficult to conceive as implantation Needs to take place so many days ( i think from memory 9- 12 ) after O again i don't know whether he was full of crap ... but gees i have everything crossed for you all ( i'm so jealous and excited you get to do it all again )
