We finally got the much anticipated call from our Genetic Counselor, and we're normal! {Chromosomally speaking anyway.} Our karyotype results show that my husband and I each have 46 normal chromosomes, with no translocations. That's good news.
It means the chromosomal abnormalities that caused our miscarriage were not inherited; they were "de novo" or new, likely due to errors during cell division.
It doesn't mean that they won't occur again; it's certainly not impossible, though from the research I've done so far, it seems improbable that we'll experience a chromosomal abnormality twice in a row. As we've come to realize, there are no guarantees -- but I'll happily accept this prognosis.
This has been the longest 13 days of my life. Who am I kidding... it's been the longest 53 days of my life. Although hearing these results don't change or lessen in any way the loss of our first pregnancy, confirming that the miscarriage was not due to any inherited abnormalities does, finally, give me some sense of hope back.
We still have a few unanswered questions, I plan on doing some more research online, and we'll likely place a follow-up call to the Genetic Counselor to obtain more information; but for now I'm going to enjoy this small bit of relief.
