Pregnancy is dated by the start of your last period. Day one of ur pregnancy is actually day one of your period, when you werent even physically pregnant at all! 2 weeks after ur period (for a normal person) you will be just barely ovulating that day. your egg will be being fertilized. then it takes about a week to implant, and another few days for hormone to build enough to be detected. so by the time you find out that you are pregnant, you are almost 4 weeks along. Even though the embryo has only been developing for 2 weeks.
