I think it is a deeply personal question and I find it offensive. When pregnant with my second child, an aquaintance asked if the pregnancy was 'planned'. She was also pregnant, with what she said was an 'unplanned' pregnancy, so I figure that is why she asked me. Nevertheless, I was a little offended at the question. We had just had an early miscarriage and the pregnancy was very much planned and wanted.

Regardless, unplanned does not mean unwanted.

Congratulations on your pregnancy!
