@Dubi Doo, I have a personal story I'll share via PM if you're interested, but if and only if you & your wife get further along AND you get 99% confirmation something is not right, or have a demise.
I'm not a medical professional, but my view is these genetic/prenatal tests, in general, especially ones which are suggestive/indicative or probabilistic as opposed to being definitive,
must be designed to be overly conservative (and therefore overly worrying to the parents). Think about it from both an economic & legal viewpoint. Parents and insurance companies aren't going to pay for tests which don't flag risk factors, and there's money to be made with re-tests and follow-ups. On the legal side, imagine the furor if the tests were not conservative (i.e., ineffective or not discerning), and instead parents were "incorrectly" told the tests showed no issues / no potential issues, only to have a large fraction of full-term pregnancies / births which weren't "perfect"?
It may sound like I'm rationalizing your situation, (but hopefully not). The majority of pregnancies remain viable, and the viability rate is higher for intentional / known pregnancies (like yours). The
overwhelming majority of pregnancies that go to term are healthy babies*. The majority of non-viable pregnancies / miscarriages result from chromosonal abnormalities. That was the case before these kinds of tests existed, and regardless of the results of such tests, or the heartache / decisions which can result from such tests. The advent of such tests themselves did nothing to change the underlying viability probabilities God / nature intended. As long as your wife is not too old, in decent health, and takes vitamins or at least folic acid, the odds are overwhelmingly in your favor for a full-term healthy baby. And even if she is older, in poor health, or poor nutrition, the odds are still
exceptionally good for a full-term healthy baby.
(*Moreover, premature births aren't significantly more risky these days.)
The above is not meant to be insensitive to your personal situation / information, nor to your feelings & concerns. Hope you didn't read it that way, and hopefully your geneticist / obstetrician conveyed something similar to the above.
I'll still say a prayer for all three of the Dubi Doos for your collective health and peace of mind.
