Pregnant with donor eggs?

Hi all, I’m 37 hubby 40. All our tests are normal (for our age) but first

IVF

we got 12 eggs only 1 PGS normal, transferred that back and it’s failed.

Now before going to wtf appt with my RE my husband and I are discussing using donor eggs. Yes it’s expensive but at least we have a better chance especially if we want to have more than 1 child.

I’m still in shock processing that I will not have my biological children but try to comfort myself at least I would carry them. Anyone here using donor eggs? How do you cope with your feelings? Have you ever felt they’re not your child?
