We got a bit of sad news in that our first embryo was lost in the process of implanting into a surrogate. It takes a total of 12-16 days from inception to know if the embryo has attached to the surrogate's uterus and this one didn't make it. The vet thinks it's because of the quality of the embryo but there are thousands of reasons that it could be, as you can imagine. We're trying again! waiting to here that there's a new embryo any day now! Will keep you posted-- thanks for your support!
