1 Work out the length of your average menstrual cycle. Day one is the first day of the menstrual period and the last day is the day before the next period begins.  Ovulation happens about two weeks before the next expected period. So if your average menstrual cycle is 28 days, you ovulate around day 14.
The most common method of calculating your due date is by taking the first day of your last menstrual period (LMP), adding 7 days, and then counting backward 3 months. For example, if your LMP started on March 20, you would add 7 days to get March 27, and then subtract 3 months to get a due date of December 27.Another way to estimate your due date is to add 40 weeks to the first day of your last menstrual period.or example, if your LMP started on March 20, you would add 7 days to get March 27, and then subtract 3 months to get a due date of December 27.
