Slight clarification question...I'm still not sure what your position would have been based on. I've never come across a rational secular argument for an abortion ban.
Every valid (note: not sound, but valid) anti-choice argument I've ever seen has relied on some sort of religious premise... e.g. something about what God has commanded or prohibited.
Secular anti-abortion arguments tend to be personal, not anything that would apply to others: personal distaste at the idea of abortion, for instance... or personal values about one's own fetus... or simply wanting to have a child. Not anything that would justify stopping someone else from getting an abortion that they wanted.
Now... there are certainly irrational non-religious people, so I see non-religious anti-choice arguments occasionally. Still, I find that - in general - people who put a lot of thought into the issue of abortion end up pro-choice unless they're constantly hearing anti-choice messaging, which usually comes from their religion.
Do you see 'abortion with some level of restriction' in the same light as anti-abortion arguments, in terms of religious foundations?
