Why are you considered two weeks pregnant at conception?

By Zaira Salvador.
Last Update: 04/30/2018

Because the weeks of pregnancy are counted from the first day of the woman’s last menstrual period. Keeping this in mind, technically the woman is not pregnant during the first two weeks of pregnancy. However, fetal development doesn’t start until conception, which occurs about two weeks later (week 4 of pregnancy).
