Does having intercourse on the day of ovulation guarantee pregnancy?

Not necessarily. The ovulation day refers to the time when a woman is most likely to conceive, but having intercourse on the ovulation day does not guarantee pregnancy. Conception can also occur outside the ovulation period. In many cases, a woman’s ovulation timing may shift due to various factors—such as emotional stress or environmental changes—leading to earlier-than-expected or unexpected ovulation. Therefore, pregnancy remains possible even with intercourse outside the typical ovulation window.
