I need more clarification on when to count day 1 of cycle. I've been counting it as first sign of any bleeding be it light or heavy. But I've been hearing conflicting information that I should only count the full AF flow as cycle day 1 and not when spotting starts? Which is odd as my period came two days late and then spotted with heavy show for two days. Can anyone clarify how I would count AF for cycle tracking please as I could be getting my dates wrong
