Its not an abortion. I don't think the symbolism is intentional either. Marcus Lindblom, Earthbound's lead translator, said in an interview that the fetus thing "never even came up." And its not like Lindblom had no communication with the game's original team. He worked very closely with Masayuki Miura, who in turn worked very closely with Itoi (Miura typed the game's entire script for Itoi who told him what to write.)
