The standard protocol for date marking pregnancy is to use the date of your LMP, not the date of conception. Conception varies woman to woman within a cycle, date of LMP is very concrete. Thus, pregnancy is always reported consistently two weeks earlier than you were actually pregnant.

OK - pregnancy is dated from the beginning of your Last Menstrual Period = LMP. So that is 2 weeks longer than from the date of conception. That is why they are adding on 2 weeks.
