How many of us have ever made a really big decision in life and then changed our mind? I suspect quite a few of us. And if there was any ambivalence in the initial decision, then a subsequent change of mind is even more possible. In which case, decisions on abortion, especially if made with some ambivalence or doubt, can also be subject to change. With surgical abortions, once a woman is in the operating theatre there is little to no opportunity to reverse her initial decision. However, the situation is different with medical abortions.
