As a mother, I'm grateful that my ob/gyn would have terminated an unwanted pregnancy, had I had one. If, for example, I had discovered myself pregnant after my ex walked out, I would not have gone through with the pregnancy. I had my existing child to think of and would not have been able to support her through my theoretical pregnancy.

The fetus is, and should be, of secondary concern to an ob. The mother is the patient and her wishes in the matter should be paramount. That includes her wishes with regard to treating her unborn child or with regard to terminating the pregnancy.
