who apparently had never heard of an unwanted pregnancy and should have known better than to lead with "Congratulations!"

Seriously. I'm happily married and living in a three-bedroom house, and when I announced my pregnancy, I had quite a few friends gently enquire whether it was something we were planning or not before they went for outright congratulations - because they know that pregnancies aren't always planned even in the best of circumstances.

Doctors should really know better.
