US abortion rate is now lower than it was before Roe vs Wade and fertility rate has been dropping in tandem with the dropping abortion rate, so I don't think that explains it.
Neither are regular hormonal pill abortions. In fact, the pill (monthly pill, not morning-after) is the most common birth control method and most prolife people support it, even though technically there’s a possibility that it may prevent implantation (if for whatever reason ovulation happens anyway).
If you want to call that abortion, then go right ahead but I think you’ll be in the minority (just like people probably wouldn’t call a natural lack of implantation a miscarriage because they have literally no way of knowing that it happened... a dewer containing 100 frozen undifferentiated embryos is just not the same as an actual child, and I think most people do not act like it is). I think the vast majority of people understand a sort of gradient between conception and birth. Most people who are prolife would be uncomfortable banning the pill and most people who are nominally pro choice probably aren’t too comfortable with later-term abortions. Reality is complicated and so are people’s opinions.
