Period timeframes

Sandy
It's difficult and cumbersome to adjust my "period schedule" when it asks "did you have any spotting" that check mark line changes to "record your menstral flow" well WTH do i put when my period is late or gets skipped due to increased exercise or increased stress levels.
Will you please tweak to say "did your period start today?" If marked NO change the day to purple and until it marks yes then change to pink. Would be a simpler way rather than ... Here change it after the fact.
