Ovulation Calculator leads to due date calendar

Familiarity with your body ensures better success when trying to achieve pregnancy. Following an ovulation calculator based on your average cycle length provides a pretty accurate time period for possible conception.

Online ovulation calculators are readily available. By plugging in the first day of your last menstrual period and your average cycle length, an estimated date is given for your next ovulation and peak fertility. This should be used along with physiological indicators of ovulation such as basal body temperature, cervical mucus, dilation and firmness and cervix position. Employing all available factors increases your chances for success.

Once conception is achieved, the same information used by the ovulation calculator is now used for your due date calendar. The most common method used to determine the expected date of delivery (EDD) takes the first day of your last menstrual cycle, adds a year, subtracts three months and adds seven days. The result is 40 weeks from the last menstrual period.

Remember that while the ovulation calculator combined with the physical factors mentioned can provide good accuracy for peak fertility times, the due date calendar is an estimate with a margin of two weeks on either side of the date.
