Just wanted to offer more support.

You are sad because you lost a daughter. You will be okay though, because you gained another son.

It must be really difficult, especially so close to the birth.

I read recently of a woman who had been assured (via Amniocentisis!) that her baby was a girl. So they did the full nursery etc... then when the baby was born, it was a boy!!! They had accidentally taken her tissue instead of the baby's! How shonky! At least you have some warning.
