Totally get the mixed feelings about it. We have 2 left, I'm pregnant with #2 and both DH & I are pretty sure we're done. However taking the step to let them go is going to be very difficult! We struggled so hard for those embryos!
I would be open to donation but DH says he couldn't do it, have our children's sibling being raised by another family.
I guess we'll keep paying the fees for a few years.
