Track Your Most Fertile Days
Understanding your menstrual cycle is the first step to getting pregnant. Your "fertile window" is the 6-day interval ending on the day of ovulation.
How It Works
We calculate your next expected period based on your cycle length, then count back 14 days to estimate ovulation. Your fertile window typically begins 5 days before this date.
