While I don't disagree with your stance here, there is always adoption...
Perhaps, but for that you'd have to convince the rape victim to go through with the pregnancy first and with the existing law, they'd probably try to get rid of it sooner or later. If abortion is illegal (or/and stigmatized), there's always other ways. Here in my country women who were rumored to be pregnant out of wedlock used to have "accidents" on their own, like "slip" in the shower and have "bleeding".
I don't endorse forcing anyone to go through a pregnancy, however there are many options for contraception, abortion used to supposedly meet the standard of safe, rare, and legal. The rare part is out the window, and ironically the most unsafe part is the fact that repeated abortions can have serious effects on a woman's ability to reproduce in the future as well as other serious medical complications.
Unfortunately abortion is being treated frivolously and there is no upper check on its abuse. Safe, legal, and rare is one thing, this is not that. Being so frivolous terminating life is a dangerous precedent to set that has implications for many, such as the elderly, infirmed, or developmentally disabled. This roads leads toward genocide if limits are not in place. Some would argue it has already been genocidal. If you examine the racial makeup of abortion statistics you can see why. I don't think abortion should be illegal, but it still doesn't make it magically ok.
