Oh baby! Calculating the due date.

You are on your obgyn or family rotation and the resident asks you to calculate the due date for pregnancy. Using Naegele’s rule and the first day of the woman’s last menstrual cycle follow the steps below:

(1) Add one year
(2) Subtract three months
(3) Add seven dates

Example the due date is 18 April 1017.
+ 1 year = 8 April 2018
– 3 months = 8 January 2018
+ 7 days = 15 January 2018
