The answer is you add one week from the first day of your last period then subtract three months. This is your due date. For example: First day of last period was Feb 13th 2007. Add one week = Feb 20th 2007. Then subtract three months = Nov. 20th 2007 will be your due date. Yes No, you add 9 months and a week to your last period date for your edd. From conception is 9 months minus a week. (38 weeks) http://www.genetree.com/about/conception-calculator.asp
