The algorithm behind Clue Conceive calculates your fertile days by continuously analyzing your tracked period dates.
It works by using your period start dates to calculate your cycle length, and to calculate the likelihood of conception in each day of your cycle. Using the highest likelihood calculations, the algorithm can then determine your predicted ovulation day and fertile days.
That’s why it’s important to track your cycle accurately and consistently to make sure your predictions are always up to date.
