Pregnancy calculator

Below is a handy and very simple calculator to use in your pregnancy. Once you have entered the basic information, it will calculate for you the date when you are likely to have conceived,  your expected date of delivery and the gestational age where your pregnancy is at this point. Please bear in mind that:

 

• For the last menstrual period, enter the date of the FIRST day of that last period.
• The  luteal phase length can be left blank, the calculator will enter this automatically

• The date format is American rather than English/European. Please enter starting with the month, then day and finally year (very important!!)

enter your dates below
