AF due date question,..

OK this may be a stupid question... but when do you girls determine when AF is due - 2 weeks after O or based on when you got it the prior month.

I know... stupid... but I would love to know what each of you do!

Re: AF due date question,..

I use FF and it gives me all the info..

But if you know how long your LP is then its that many days past O that you would expect AF (or hopefully not )

Re: AF due date question,..

I use my monthly cycles and it calculates your average of when you should get AF...there is also fertility friend...you put in when you get AF and how long your cycles usually are...then you keep track of them and it averages it out.

Re: AF due date question,..

I use a little bit of both. When I had exactly 29 day cycles then that was that, I knew when she's be here. But now that my cycles are a bit off I use an app on my iphone as well as FF. They both give me my average cycle length and predict when she's a comin'!

Re: AF due date question,..

I've got a 26-day cycle, always. MMC sends me a reminder in an email to let me know when to expect her.
