Estimated Ovulation Day vs Cycle Length
Formula
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.
Esempio Risolto
A woman with a 28-day cycle.
- 01Ovulation day = 28 - 14 = day 14
- 02Fertile window start = 14 - 2 = day 12
- 03Fertile window end = 14 + 1 = day 15
- 04Fertile window = days 12-15 (4 days)
