Everything you need to know
Our Fertility & Ovulation Tracker helps you understand your body's natural rhythms. By tracking your cycle, you can identify the window of time when conception is most likely.
How it works:
Most cycles range from 25 to 35 days. Ovulation generally occurs 14 days before your next period begins. Your fertile window includes the days leading up to ovulation when sperm can survive in the reproductive tract.
