I disagree and feel that anyone should be dissuaded from aborting at this stage unless there are very good reasons why they need to. Someone 'on the fence' like OPs daughter will probably have a far harder time dealing with it and a much bigger chance of regret. I know nobody who has aborted at this stage who isn't traumatized by it - not only the procedure but the reality of how developed the baby was when they did this. I hate that in modern society, abortion is such a sensitive topic that we have to pretend it's all fine and great and cheer them on to the point of not even giving much needed advice and support, and not being allowed to say the truth. At 18 weeks, it is too late to abort unless absolutely necessary and if OP's daughter doesn't regret it already, she will probably really struggle with it in the future. ESPECIALLY because it sounds like she's not making the decision for herself, but rather a spur of the moment decision due to stress and anxiety.
Then it’s just as well she’s not under your influence (if indeed she exists and this is not actually a wind them up and watch them go troll thread). She’s a woman that needs support, not an opportunity to advance your agenda.
You really don’t know enough about this woman to say either way whether it’s the right decision for her. That’s why she needs neutral counseling to help her decide what course of action is right for her. That may be abortion, or it may not be. That’s for her to decide, no one else.
Just because you don’t personally know anyone that hasn’t regretted a late term abortion doesn’t mean they don’t exist (hell, there’s at least one in this thread you’ve ignored), as you know. The plural of anecdote is not data. Abortion may cause trauma, it may not. It may cause trauma, but a lesser trauma than one experienced by being compelled to go through an unwanted pregnancy. No one can predict what someone else will feel, and we shouldn’t try to. What we should do is respect the rights of people to make their own choices in such matters, even if we may think they’re wrong. We’re not the ones that have to live their lives or live with the decisions they make.

Do we? I’m not pretending, and you seem to be fairly free with your opinion. Although this is the classic pro life persecution complex. Disagreeing with your opinion isn’t shutting you up or preventing you from having it (clearly, because here you are). It’s not some great conspiracy theory, you’re just salty because you’re being disagreed with.
and not being allowed to say the truth
What truth would that be? Again with the complex. You have an opinion, you’re not endowed with some great access to universal truth.
