We had a very similar experience with a traumatic series of screenings during my pregnancy. I don't want to recount the whole thing but basically because one ultrasound tech saw something one time we got on this whole other track of intense additional tests, screenings, and genetic counseling. We were told we had a less than 20% chance of a healthy, normal baby. My OB was not familiar with the diagnosis and handed us off to the prenatal specialists who are all hammers looking for nails. This continued all the way into late 3rd trimester where they still couldn't find anything actually wrong and wanted to look at the heart again. At which point we told everyone and their dog to FOADIAF.

My son is 1000% healthy and normal. My partner and I are now completely convinced there is such a thing as too much information. We were in no way helped by any of the early screenings aside from the MaterniT21 genetic screening (which said everything was normal, which it was)

Next pregnancy, we are only getting said genetic test, the regular belly measurements done and the ONE 20 week ultrasound to be sure there are the appropriate number of limbs. Otherwise, I want everyone to stay the hell away from me.

I'm not sure what this comment serves other than to tell you you are NOT alone in this experience. You and your wife should make a game plan for what testing you want done, and opt out of everything else.
