The ovulation window typically spans about six days: the five days before ovulation and the day of ovulation itself. Sperm can survive in the female reproductive tract for up to five days, so having intercourse during this window significantly increases your chances of conception.
- Know Your Cycle Length: The first day of your period is day one of your cycle. The length of your cycle is the number of days between the first day of one period and the first day of the next.
- Estimate Ovulation Day: Ovulation usually occurs about 12-16 days before your next period. If you have a 28-day cycle, ovulation might occur around day 14. If you have irregular periods see our article on irregular periods and conception.
- Identify Your Fertile Window: Once you've estimated your ovulation day, count back five days to find the start of your fertile window.
