There is no "most likely" here. At the time this women killed her child, he or she had a beating heart and, more importantly, a functioning nervous system. The nervous system forms between three and five weeks after conception. Once cells differentiate into tissue types, they function as that tissue type. Thus, nervous system cells send messages to each other. Those messages are what we subjectively feel and think. That baby was aware until his or her life was snuffed out.
I'm also stricken by an admission that this woman made regarding her decision to get pregnant. She did so for the man's benefit--he did not respect her desire to use birth control, and she had sex with him anyway. Who really benefited from her willingness to abort her baby? For all of the claims of feminism, it looks to me like readily available abortion has made women into sex objects more now than they ever were before the ramping up of "feminism" in the 1970s.
