Ovulation is the release of a single, mature egg from a follicle that developed in the ovary. Ovulation usually occurs regularly, around day 14 of a 28-day menstrual cycle. Once released, the egg is capable of being fertilised for 12 to 48 hours before it begins to disintegrate. This is the most fertile period of your cycle. During ovulation your chances of conception are highest.

Ovulation usually takes place approximately 14 days after the beginning of your menstrual cycle (the first day of your last period). The exact time of ovulation may vary within your cycle, because ovulation can be delayed by a number of factors such as stress, illness, diet, or increased physical activity.

Your fertile period starts about 4-5 days before ovulation, and ends about 24-48 hours after it. This is because sperm can live in your body for approximately 4 to 5 days, and the egg can live for 24 to 48 hours after being released. You are most fertile on the day before and the day of ovulation. Knowing your fertile days can help you increase your chances of getting pregnant.
