MoonDragon's Pregnancy Information: Labor & Delivery Tutorial




This is a calculator that tells you your pregnancy due date.
It helps you to plan when the stork will make its appearance.


Click on The Pregnancy Calculator Icon above.

On the calculator page, click on one of four options available.
  • Calculate the due date based on the first day of the last menstrual period.
  • Calculate the due date based on the date of conception.
  • Calculate the current gestational age based on the due date.
  • Calculate the required conception date based on the due date.

Enter the appropriate date for the option you have chosen.

Fertilization usually takes place 14 days before your next period. If your menstrual cycle is longer or shorter than 28 days, enter the length of your menstrual cycle (only available for Option 1).

Use the slide bar above the calculator to show fetal development from 0 to 40 weeks gestation. It will show you your baby's development and information about the stage he/she is in for that week of gestation.
