You ovulate for about 12–24 hours, but your “fertile window” is usually around 5–6 days each cycle.

The quick scoop

  • Ovulation itself (when the ovary releases an egg) lasts roughly 12–24 hours; after that, the egg can no longer be fertilized.
  • Fertile window : Sperm can live in the reproductive tract for up to about 5 days, so you can get pregnant from sex in the days before ovulation plus the ovulation day itself (about 5–6 days total).
  • In a “typical” 28‑day cycle, ovulation often happens around day 14, but for many people it’s earlier or later and can change from month to month.

Key timing points

  • The egg survives about 12–24 hours after release.
  • If sperm are already present in the days before ovulation, they can fertilize the egg during that short 12–24‑hour window.
  • If the egg is not fertilized, it breaks down and is shed with the uterine lining about two weeks later as your period.

Example to picture it

Imagine a 28‑day cycle:

  1. Days 9–13: Fertile window starts as sperm from sex on these days can survive until ovulation.
  1. Day 14: Ovulation day; egg is available for about 12–24 hours.
  1. After that 24‑hour period, pregnancy from that cycle is unlikely if there is no fertilization.

If your cycles are irregular or you’re trying to conceive (or avoid pregnancy), it’s best to talk with a healthcare provider about tracking methods (like ovulation tests, basal body temperature, or apps) tailored to you.
