Understanding Your Cycle

Ovulation is the brief window during your menstrual cycle when an egg is released and is ready to be fertilized. Knowing your exact fertile days is the most natural and effective way to either plan for pregnancy or simply understand your body's rhythm.

The Fertility Phases

The Fertile Window: The 5 days leading up to and the day of ovulation. This is when your chances of conception are highest.
Ovulation Day: The peak day when the egg is released. It typically survives for only 12 to 24 hours.
Luteal Phase: The time after ovulation until your next period starts, usually lasting a consistent 14 days.
