Regroup With My RE: What Happened With the Miscarriage?

So I had a long phone conversation with my RE today--the first one I've had--about what happened with the miscarriage (which you can read about {here} and {here}). 

First off, I am so, so happy to report that it looks like we will be getting some help from our insurance in terms of the tests etc. from this point forward. Apparently I have moved from an "infertility" diagnosis to a "recurrent pregnancy loss" diagnosis, and insurance generally covers the latter. It's silly, but somehow the fact that my insurance is willing to pay for some of this (hopefully) makes me feel less invisible and less alone. I'm so used to paying out-of-pocket for 100% of everything...I don't know...it just feels like now somebody cares about what is happening to me vs saying "this isn't a medical issue, deal with it yourself."

It seems like the big question my RE is asking is: Was it my body that caused this, or a genetic abnormality in the baby? The genetics aren't back yet (although I'm understanding more why it's good to have them...and the fact I don't have to pay for them [probably] makes me feel better about the fact they were done). My RE said if there IS an abnormality on the test, we don't need to do anything else except try again. (He also said the timing of my miscarriage [he called it "late"] is unusual if it's due to a genetic abnormality). If there is NOT an abnormality on the test, it could mean 1) there actually was one and the test couldn't pick it up (because the baby had been dead in my body for weeks), OR, 2) that it's me. In which case he wants to do a bunch of tests to rule out autoimmune/blood clotting issues (that apparently can be managed with medication if I have them). He also wants to do a genetic test on my husband that I guess they did for me at some point but not for him.

Anyway, all this just gets more and more complicated. Since the phone call I've kind of lost the zen I've had for the past week or so where I've just been focusing on nutrition and visualization and yoga etc...you know, stuff you can control. All this medical stuff has always felt pretty overwhelming to me...don't know how to relax more about it....need to figure out a way. 

I guess we'll just be taking this next part step by step. Grateful there are still options and that my doctor's trying to get to the bottom of all this...
