My OB recommended that we might want to do cvs or amniocentesis because of a previous pregnancy loss that resulted from a genetic abnormality. After that loss, I met with the genetic counselor, who told me that our particular abnormality (triploidy plus a deletion of one chromosome 10) was a random event and did not increase our chances of future loss. They checked for translocations, genetic abnormalities that can be inherited, and didn't find any. The OB said in contrast that having a previous loss due to a genetic abnormality increases your risk of future genetic abnormalities and we should weight the benefits and costs of invasive testing.

Has anyone else received a similar recommendation? Nearly all miscarriages are caused by genetic abnormalities, so this logic would seem to suggest that anyone with a miscarriage should consider cvs or amniocentesis in future pregnancies, but I don't know if that's the standard recommendation. I'm going to do NIPT, but it only tests for trisomies 13, 18, and 21 and the doctor suggested considering invasive testing as well since it can look for many other conditions.
