What Happens After an Embryo Transfer?

Once you complete your embryo transfer, you will have approximately 1½ weeks to wait before a pregnancy can be detected. The following tables outline an approximate timeline for what happens during a successful pregnancy after a 3-day transfer (3dt) and a 5-day transfer (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	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

5-Day Transfer- Blastocyst

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
Six	Human chorionic gonadotropin (hCG) starts to enter the blood stream
Seven	Fetal development continues and hCG continues to be secreted
Eight	Fetal development continues and hCG continues to be secreted
Nine	Levels of hCG are now high enough to detect a pregnancy
