How Ovulation Tracking Works
Ovulation occurs when an egg is released from the ovary. By tracking your cycle length and knowing that the luteal phase (post-ovulation) is typically 14 days, you can estimate when ovulation will occur. The fertile window includes the 5 days before ovulation and the day of ovulation itself.
Key Factors Affecting Your Cycle
Cycle length can vary from 21 to 45 days. Stress, diet, exercise, and health conditions can affect timing. For the most accurate results, track your cycle for several months to determine your average length.
Ovulation Calculation Method
Ovulation typically occurs about 14 days before your next period. The fertile window spans 5 days before ovulation through 1 day after.
