Yes, talk to the clinic and just treat this as plan B. Hope you don't haave to go down this route. I know about this from someone who accepted a donated embryo. Both of them are infertile. This might be the rule in Austraila or clinic specific. Embryo donation is hard to find. Most choose to have a preference as well.
South Africa might be a bit open. I know the donation there is completely anonymous (ie, child can't find out the biological parents when they turn 18). While not donated embryo, I know someone went there to have a chosen sperm and egg donor to create an embryo.
