If you were seeking to get pregnant via in vitro fertilization, what would you do if you found out that the wrong embryos were implanted?

Apparently this happened in Connecticut last year. A technician at a reproductive services center took the wrong embryos from a freezer to implant in a woman. (Apparently, the source of the embryos had the same last name as the woman in question.) What would you do under these circumstances? Would you want to keep the pregnancy, or take the morning-after-pill and try again with the correct embryos? (Men, what would you want your partners to do?)
