I suggest the pro-choice side accept the legitimacy of ethical concerns, but argue on two fronts: 

1. that the foetus only becomes a person at some time in the process of gestation, and that we can set a reasonable time period to that before which abortion is not murder; 

and 

2. that forced pregnancy and childbirth are extremely painful and damaging experiences both mentally, emotionally and physically, akin to torture, and therefore should be considered as akin to a situation of  self-defence which justifies abortion. Few people would expect someone to submit to torture in order to save someone else's life, so no one should expect a woman to submit to forced pregnancy and childbirth, even to save the life of someone not yet born.
