Well , thanks, Pandora . I  did read it .  Certainly a marvel of legalism , if one is a fan of such things . To me it seemed heartless in its specificity .I am not faulting you , Pandora .  Since medical science has no way yet to pinpoint conception I do not see how theology can rely on a moment in time as basis for failure to give the raped woman the very simple decision to take medication .  
A forced pregnancy creates a possibly rejecting environment for the unborn .  Great care needs to be taken in finding adequate parents for the newborn .
 And what will happen should this person , now an adult  inquire as to biological parents ?  
This situation requires the wisdom of Solomon , not slick theological answers based on probabilities .
