Ovulation typically occurs 14 days before your next period. For a 28-day cycle, that's around day 14. For a 30-day cycle, around day 16.
The fertile window is about 6 days: the 5 days before ovulation plus the day of ovulation. Sperm can survive up to 5 days, and the egg lives for 12-24 hours after release.
Ovulation calculators provide estimates based on average cycles. For more accuracy, combine with ovulation predictor kits (OPKs), basal body temperature tracking, or cervical mucus monitoring.
