There's some legal murkiness I could see coming from that, but in principle it seems like something you would have to prosecute after the individual was born.
If a fetus isn't a person, then there's no victim. The potential of a victim isn't the same as a victim. The intention for there to be a victim doesn't even create a victim.
I think about the closest thing you could argue for would be that if a person knew they were pregnant, could have aborted but chose not to, and engaged in behavior that demonstrably caused harm once there was a live person, then maybe you could argue some type of negligence. But even that feels really close to a slippery slope to me, and makes me too uncomfortable.
If for no other reason than it could create a situation where someone is prosecuted for knowingly reproducing while having a measurable statistical chance of a heritable birth defect, or just being above the age where down syndrome becomes more likely.
