This may be a little convoluted, but bare with me.
1. In a recent thread, we discussed a man who administered an abortive drug to his girlfriend causing her to miscarry, as the drug is meant to do.
2. In that case, the man was charged with murder - although according to all those who are pro-abortion will tell you that a fetus is not a human or a person, so murder seems to be misplaced.
3. The majority of women felt that the man should be charged with some form of assault or attempted murder because the drugs are dangerous if not taken appropriately and could kill the woman or at least cause her physical harm - we can agree on this.
4. If I understand the OP correctly, you're talking about a woman administering some substance to herself that will cause a miscarriage or damage the fetus in such a way that it will be stillborn or not come to term. Keep in mind that those who support abortion always claim that a fetus is not a separate entity, it is simply a "growth" attached to the woman's body and part of her body until such time as the fetus becomes viable.
5. If I understand the OP correctly, this is not a doctor prescribed action since no doctor would administer drugs to purposely brain-damage a fetus. That is outside the realm of what I would consider normal chemical abortion.
6. If we agree that this is not the normal process, similar to the previous case of the man administering the drug to his girlfriend outside the normal process, this also has the potential to physically harm and/or kill the woman.
7. When another person physically harms or potentially kills someone it's a crime, usually called attempted murder, when a person physically harms or potentially kills themselves, that's usually called suicide or attempted suicide.
8. Since suicide is illegal in all jurisdictions, at least that I know of, this would, therefore, be a crime against one's own person. Such crimes are not usually, if not never, charged with a crime but mandated by a court to get psychiatric treatment and care, then this would be the appropriate action to take in connection with any woman who took it upon herself to harm her body or any part of her body.
Therefore, in summary, as related to the OP, my answer would be no.
