A lot of uncaring boyfriends are slipping their girlfriends abortion pills these days. But hey, if you think this can't be stopped and there's no point bothering to make it illegal...
It IS illegal, it's assault......see, when you do bad things to people like giving them drugs without telling them that's assault...yes, even if it's "only" women you are doing it to...
Your post is a good illustration for why it is an intolerable idea to regard life as beginning at conception in the legal field. I doubt most Pro-Life supporters have ever given the social impacts of such a law a second thought. If enacted, it would become a legal & social nightmare.
