Many refer to this period of time after your embryo transfer as the dreaded two week wait because this time period between embryo transfer and your first blood test for pregnancy can seem like forever! After your embryo transfer there's lots happening inside your uterus. In about 7-14 days you will know if your transfer was successful and pregnancy can be detected. Below is a table that will outline the approximate timeline regarding what's actually taking place during a successful 3-day transfer also known as a (3DT) and 5-day transfer also known as a (5DT)

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 - Embryo development continues and hCG continues to be secreted

Ten - Embryo development continues and hCG continues to be secreted

Eleven - Levels of hCG are now high enough to detect a pregnancy

5-Day Transfer

Days Past Transfer (DPT) - Embryo Development

One - The blastocyst begins to hatch out of its shell

Two - The blastocyst continues to hatch out of its shell and begins to attach itself to the uterus

Three - The blastocyst attaches deeper into the uterine lining, beginning implantation

Four - Implantation continues

Five - Implantation is complete, cells that will eventually become the placenta and fetus have begun to develop
