To maximize the chance of pregnancy, determine the most fertile days, which is right around ovulation. On an average, the first day of a menstrual period occurs 14 days after ovulation. For a 28 day cycle this means ovulation occurs 14 days after the first day of a menstrual period. However, if cycle is shorter or longer than 28 days, the number of days from first day of menstrual period to the next ovulation varies accordingly. This calculator will help determine the most fertile days.
