Let's not assume that everybody looking for an abortion is not married.
Scenario C
Wife: (Thinking to herself after confirming her pregnancy) I'm pregnant, I don't want another baby and blurts out to husband I'm off with the girls shortly on a girly break, couldn't resist the low airfares and I'm worth it.
Husband: Off you go, enjoy your break, you deserve it.
Abortion occurs and nobody is any the wiser. [Please dont take offence, I'm merely adding to previous posts].
That's quite possible and there's no way of legislating for it.
I find the whole topic difficult to square and I would certainly not judge anyone who has had an abortion; it is a massive decision and can have a life-long impact on people.
