Pregnancy Calculator

Our pregnancy calculator allows you to calculate important dates for your pregnancy, such as your current gestation, your Estimated Due Date (EDD), and when you should schedule Ultrasound Scans (after consulting with your midwife or Doctor). 

To use this calculator please enter ONE of the following: Your EDD; or if you don't know that yet, you can enter the date of the first day of your last period.


Estimated Due Date (EDD)

If you have already had your first Ultrasound scan, you will likely have been given an EDD. Enter it here (dd/mm/yyyy).

1st Day of Your Last Period

Use this option if you don't already have an EDD. Enter the date of the first day of your last period (dd/mm/yyyy).
