Using a Reverse Due Date Calculator to Determine Your Conception Date

Reverse Due Date Calendar

A reverse due date calculator, also known as a conception date calculator, will estimate when you conceived and help you know how many weeks pregnant you are.

o you know that you are pregnant, and you know your due date, but a reverse due date calculator will tell you when you actually conceived.

Using a Reverse Due Date Calculator

To use a reverse due date calculator, just enter your due date, and the calculator will give you the possible conception date of your baby.

This date is not exact, but it can give you a pretty reasonable idea of the range of possible dates.  You ovulate 14 days before your period begins.  You can get pregnant by having intercourse up to 5 or 6 days prior to ovulation, so there is a window of time in which you may have conceived.

Preparing for Baby Using a Reverse Due Date Calculator

Knowing your due date and conception date is a good start, but many people feel like they can’t really get prepared for their baby until they know its gender.

Most women don’t have their first ultrasound until around 20 weeks, and it can be really difficult to wait that long to find out.  Even then, the accuracy of gender prediction by ultrasound varies greatly depending on the baby’s position during the ultrasound and the skill of the technician performing the ultrasound.

Although the accuracy is questionable, one interesting method for predicting your baby’s gender is the Chinese gender predictor chart.  According to legend, the original Chinese gender predictor chart was buried in a royal tomb near Beijing over 700 years ago.

The chart uses the mother’s age at the time of conception and the month of conception to predict the baby’s gender.  Some versions of the chart require that you use the mother’s Chinese age at time of conception and the Chinese lunar month of conception, but a tool on the site will help you determine those factors.

While this predictor is fun to try, you probably shouldn’t start painting the nursery pink or blue based on its results.  The only definite way to determine gender is through amniocentesis, and a doctor won’t perform amnio simply for the purpose of gender prediction.

You could also try the Intelligender gender prediction test.  This is a urine test that can be used as early as 10 weeks to predict baby’s gender.  Intelligender has an average accuracy rate of 90%.  At the very least, it can keep your curiosity at bay until it’s time for your ultrasound.

Using a Reverse Due Date Calculator to Develop a Personalized Pregnancy Calender

A personalized pregnancy calendar is a fun way to keep track of all the milestones of your pregnancy and your baby’s development.  You can use a reverse due date calculator to get you started in creating a personalized pregnancy calendar.  You’ll need to enter:

  • your due date;
  • your conception date; or
  • the date of your last menstrual period.

Once you have the basic information set up, a pregnancy calendar can help you keep track of how far along you are, baby names, and more.
