No: That was the day your egg was impregnated with semen

Dates: the weeks of pregnancy are actually figured from the last period not the date of conception so it is usually 2 weeks longer than the actual age
Dr. Phillip Goebel
Emergency Medicine 16 years experience
From LMP: Dates are calculated from your last menstrual period, so the date of conception is paradoxically at the 2 weeks gestation mark. This confusion is a left over problem from when we had nothing but menstrual cycle to date pregnancies.
