If you want to become pregnant, an ovulation calendar can help you to map out the best times to try for a baby.
Ovulation refers to the release of an egg from a woman's ovary, and tends to occur about 14 days before the start of your next period. You are most fertile around the time of ovulation. While an egg survives for only about 24 hours after it has been released, sperm commonly live inside the female genital tract for about 3 days (and sometimes for up to 5 days). This means that sperm deposited in the genital tract several days before ovulation can be alive and can fertilise the egg when it is released.
Follow these steps to see your ovulation calendar and find out when you are most fertile.
1. Enter the date of the first day of your last menstrual period.
2. Enter the length of your usual cycle (in days).
Days To determine the length of your cycle, count the number of days from the first day of your period (day 1) to the day before your next period starts. Remember, not all women have a 28-day menstrual cycle.
