Lots of people have an abortion and then later have children. Their motivation is not to avoid damage but to delay becoming a parent for financial reasons.
I think it takes a particularly skilled mental gymnast to have an abortion for financial reasons and then turn around to say we shouldn't eat honey because we're exploiting the bees.
That is to say, I'm far more sympathetic to an argument from a vegan who also happens to be pro life, as that seems to me like the more consistent position: pro human and pro animal life.

Later? The majority of women who have abortions are already mothers. [1]
"I don't eat meat or abort fetuses, but I don't want laws or norms saying we can't either." There's no serious ban in meat being discussed.
Raise it yourself or put it up for adoption are the first two options that come to mind if the resulting child is the problem.
C-section or risk popping it out the normal hole are the obvious alternatives if medical complications are the problem.
Personally I don't have a problem with abortion but if you want alternatives then there you are.
What are the alternatives to abortion if the problem is not the child existing but the birthing process?
1. C-section.
2. Do nothing and let the thing come out the existing hole knowing full well that one of the side effects may be death of the mother, infant or both.
In this day and age the latter really isn't an option that's seriously on the table but back in the day abortions/c-sections weren't really a thing or were more risky and you couldn't tell in advance if there would be complications so that risk was just accepted.
Edit: FWIW I am pro-choice (since apparently we can't have a discussion about alternatives to abortion without assuming other people's opinions on the issues).
There's countless situations where I could judge someone's behavior as a thing they should never do, even though I'm not in their shoes, but this isn't one of them. If a mother wants to abort, that's just on her! Maybe the suffering of the fetus is tragic, but it's all her choice and I can't really judge her because I'm not her. I accept I can't prevent every bad or possibly bad outcome and end all suffering.
Edit: I appreciate dialog on the specifics of these things. I think people just... assume that because they're all on the same "side" they come to the same beliefs and conclusions from the same reasoning (or that everyone around them has a reasoning to begin with) and that can end up causing huge problems.
Also, abortions weren't really a thing? Are you sure about that? I'm pretty sure it's only recently[1] that abortions were distinctly not a thing.
