Hi Dr. Smith, I am currently undergoing a FET cycle. I have 3 five day blastocyst on ice. I was wondering when implantation would likely occur? Thanks!
At the time of thawing, the blastocyst stage embryos are already capable of attaching and initiating implantation. Attachment of the embryos to the endometrium will occur within 24 hours of transfer, while the implantation process will continue over the next 10 days. Good luck.
