Ban abortion for every instance except for health concerns, and that's it. Anything else would be to straddle the fence.
Abortion will never be banned in the US because it's contrary to the interests of the right wing to do so. They would lose their bread and butter issue - it will never happen.
It would also never happen because the citizens of any state that favoured a complete ban would wake up and smell the coffee really quickly if such a ban had a good chance of becoming a reality. You know, sort of like those loose leftist folks up in South Dakota did.
