Thank you so much for your response! Very informational! We had our 3 day embryo transfer this past Saturday so I plan on taking my HPT on Sunday :) Praying for positive results!
When I had my 5-day transfer, I was also wondering how early I could test. I tested 5 days post transfer with a hpt and got a negative. But both of my betas were positive, so it must have been too early. Now I am 14 weeks pregnant! :)
During this time, my friend sent me the following information, which was SUPER helpful! Hopefully it will help you too.
Best of luck and lots of baby dust!!
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
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
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

Seven
Fetal development continues and hCG continues to be secreted
Eight

Nine
