I'm sure this question has been asked 1000 before but I'm going to ask it again!
If you wake up and bam, AF is there that's day 1.
But what if she doesn't 'pop in' till around 4 in the afternoon?
Would you count the next day as day 1 or the you start bleeding as day 1, even though it was late in the afternoon?
I want to be able to track my cycles properly to pin point O day.
Would love your feedback and advice.
