I found this online and thought it was kinda cool, so I thought I'd share it here...

3-Day Transfer

Days Past
Transfer (DPT) Embryo Development
One The embryo continues to grow and develop, turning from a 6-8 cell embryo into a morula
Two The cells of the morula continue to divide, developing into a blastocyst
Three The blastocyst begins to hatch out of its shell
Four The blastocyst continues to hatch out of its shell and begins to attach itself to the uterus
Five The blastocyst attaches deeper into the uterine lining, beginning implantation
Six Implantation continues
Seven Implantation is complete, cells that will eventually become the placenta and fetus have begun to develop
Eight Human chorionic gonadotropin (hCG) starts to enter the blood stream
Nine Fetal development continues and hCG continues to be secreted
Ten Fetal development continues and hCG continues to be secreted
Eleven Levels of hCG are now high enough to detect a pregnancy
