Date of Conception: There are many calculators available online to give an educated guess as to conception date if you've been given a due date, which can be determined by either last menstrual period or an early ultrasound. If you use http://www.Baby2see.Com/conception_calculator.Html, it gives dates of conception from mar 5th-13th, which works out just right w/mar 10th. Fyi LMP of feb13th gives due date of nov20th.
