About Dec 5: If you are due aug 29, then conception would have happened about dec 5. If your cycles are about 28 days, the first day of last period would have been about nov 22.

After December 6: Utilizing naegele's rule and accounting for ovulation time of 14 days after date of last menstrual period (if your cycle is 28 days), it puts your conception date after december 6, 2012 if you're due date is august 29, 2013. Naegele's rule estimate edd from patient's dlmp, by adding one year, subtracting 3 months, and adding 7 days from patient's last menstrual period in order to obtain edd.
