So if you have questions related to any of those fields, please seek out the advice or counsel of a qualified physician or attorney.A pregnancy conception calculator can help you determine your pregnancy conception date, which is the date your baby was conceived, based on the due date of the pregnancy.

Note that this conception calculator generates conception dates based on averages and therefore can only be considered to be estimates. My expertise is creating online calculators based on known formulas, not obstetrics, gynecology, or paternal law.Instructions: Select the month, day, and year your baby is due, and then click the "Calculate Conception Date" button.Mouse over the blue question marks for a further explanation of each entry field.Women who experience regular period cycles typically conceive about 11-21 days after the first day of their last menstrual period.Determining the exact date of conception is difficult and so your conception date is mostly an estimate based on your period cycle.Typically, your estimated due date is about 40 weeks from the first of your last menstrual period, but this is just an estimate.

It is common for babies to not be born on their estimated due date.

This process is based off of the assumption that every pregnancy is typical, that the pregnancy lasts 40 weeks, and that each woman has a 28 day cycle.

In order to calculate the estimated conception date, the calculator will use the last menstrual period date, date back three months, and then add seven days to determinate your due date.

Want to know what date and day of the week you were likely conceived on?

Simply select your birthday (or due date if you were born premature or late) and click the "Calculate" button.

It also includes a countdown meter and printable calendar.
