Educational only — not medical advice. If you have urgent symptoms, seek medical care.

Timing is a common source of confusion. The goal is not perfection—it is consistency.

A simple mental model

  • Ovulation is the release of an egg.

  • Sperm can survive for several days inside the reproductive tract.

  • The “fertile window” is the set of days when intercourse is most likely to lead to pregnancy.

If your cycles vary, it can help to focus on patterns over time and use tools (like LH tests) if appropriate.
