Estimated Ovulation Day vs Cycle Length
Fórmula
## Ovulation Estimation **Ovulation Day = Cycle Length - 14** The luteal phase (post-ovulation) is typically 14 days. The fertile window spans from 2 days before ovulation to 1 day after. ### Fertile Window Sperm can survive up to 5 days, but the most fertile period is the 2-3 days before and the day of ovulation.
