Frequently Asked Questions
In a standard cycle, ovulation occurs approximately 14 days before your next period (the luteal phase). Your fertile window spans the 5 days leading up to ovulation plus the day of ovulation itself (a 6-day window), because sperm can survive inside the reproductive tract for up to 5 days.
The highest probability of conception occurs during the 2 days leading up to ovulation and the day of ovulation itself.
