You are likely to be most fertile on the day of ovulation and during the 4 or 5 days just before ovulation.

Sperm can live for a few days and the egg can live about a day. Most experts suggest you try every other day or every day starting about 5 or 6 days before you expect to ovulate. Continue up through the day of ovulation or the next day.

How is my estimated date of ovulation calculated?

On average, a woman with a regular 28-day cycle ovulates on about the 14th day of each cycle. If a woman’s cycle is longer or shorter than 28 days, the predicted ovulation date is changed accordingly. For example, during a 24-day cycle (4 days shorter than the average), ovulation takes place on about the 10th day. Similarly, changes are made in the opposite direction for cycles longer than 28 days. Stress, illness, and other things can also affect the timing of ovulation. Irregular cycles or cycles that are shorter than 21 days or longer than 35 make calendar prediction of ovulation unreliable.
