i had a quick squizz, but i couldnt find a thread to help me..

i used the BB due date calculator, but i was confused where it said Cycle & Leutal (sp) im not 100% what that means, so im not sure if my date is accurate! i just left the default numbers in there, and entered my date.. is this correct?

also, i never realised it was calculated using the first date of your last period!
i really have only basic knowledge of the whole ovulating thing, ive never paid much attention to it to be honest!
