@Butterfly39, our donor was 26. She had donated once before, that resulted in a twin pregnancy and also had two kids of her own. She wasn't our first choice and we had a few false starts with other selected donors. She actually stepped in when our first choice had been found to have a really low amh and hence was probably facing fertility issues herself. She was a first-timer and I had requested they test her AMH.
The FS over there recommended to keep age at 27 or under. It is still a game of luck but the odds are much better with younger eggs. We fluked upon some fertile goddess who blessed us with 22 blasts. Her previous cycle had had 12 eggs and 6 fertilise. We could have never expected the kind of result we had. We were just incredibly lucky.
As a new Mum I can tell you that any worries about whether you will love the child the same go out the window when they come into your world.
