@Canuck1 After all your hard work and patience to get your embryos over to Canada I really hope your next transfer is THE one. CFCs success rate with FETs is around 50 to 60% I believe. Curiously, have you asked Kimenthra if any other recipient has had success with the donors sperm? What immune issues have you been tested for? Possibly a silly question to an experienced ttcer but do you POAS early on to see if implantation may be occurring?
