Unfortunately most early m/c's are due to chromonsonal abnormalities that you can not control. I think the testing is important because if it turns out there are no abnormalities you can start exploring other explanations.
For example I have a blood clotting disorder and I now go to a perinatal specialist to treat it.
That's my opinion anyway. But honestly there is no answer you will get from the testing that will help you emotionally. There's no explanation good enough for such a heart breaking loss.
But it might prove to be important in the future when you're ready to try again.
I have heard that same thing about chromosomal abnormalities and early m/c. I too agree that the testing is a good idea as it may identify an abnomality that can be "helped". I know that some ladies with clotting disorders end up needing to take baby aspirin. Just a thought.
I am so sorry for your losses. I hope the testing helps give you some piece of mind. I asked for an autopsy on my daughter even though I knew she came in contact with fifth disease. I just wanted as much info as I could possibly get. I'm still waiting for my results but have heard that the results don't really tell you much.
They told us both of our tests were normal. The test did mention something about my 14th chromosome having an elongated short arm...whatever that means. But they still listed it as normal. The chromosome testing was just blood work...it took a few weeks to get back the results. No biggie.
