I am not sure I can even understand the point. You try a new psychiatric drug - you do not know if it would be a success or not. All psychiatry is trial and error. You may have to suffer through very severe side effects and discontinue the trial. You cannot predict in advance what will work. Likewise, here - you try and see through testing whether the pregnancy is with issues and then decide whether to discontinue based on the results of the tests. What is the difference?

How can you not think abortion before getting pregnant after 35? It is just part of the process. It is a consequence of the increased risk of the Down syndrome and, I have just looked it up, the rate of elective abortions after testing positively for Down is close to 100% in UK, US, and continental Europe, which is to be expected.

So sure, an abortion and some period to heal after it delays the process and I would not be getting younger, so it would be frustrating, disappointing, and uncertain, but a lot of things in life are frustrating, disappointing, and uncertain.

So that is not an issue.

Prenatal testing is not 100% accurate - that is the issue. Testing may fail to detect Down. So with that risk in mind, one has to think many times. If testing were without error, then I would not mind one or two abortions (the likelihood of Down on more than two trials in order is extremely small) as long as I could be assured that I definitely would not carry a Down pregnancy to term.
