Understanding Ovulation
Ovulation typically occurs about 14 days before your next period (luteal phase). The fertile window spans approximately 5 days before ovulation and 1 day after. Sperm can survive up to 5 days in the reproductive tract, while the egg is viable for about 12-24 hours after release.
