I'm sorry to hear about your second loss

It's very hard to go thru this sort of tragedy once, let alone multiple times. I hope that your heart heals quickly
Not to flip sscript quick... but I have to say a few things about testing... (from my experience and as well as so many others)
A friend of mine asked me prior to all the testing I had with an RE for recurrent loss.... "Do you think you're going to be ok if they DO NOT find anything?" I couldn't honestly answer that because I SO wanted to find out if there was something wrong! We always assume there is something wrong with US if we have multiple miscarriages... but it could be a mystery we would never know, or genetic, or DH's swimmers. So many possibilities!
Anyways jumping forward....
At some point you want to really know if there's something wrong (allot of us have) and in some small way you hope there's an answer (like something actually being wrong and easily treatable), but to be perfectly honest allot of times there is NO answer (all tests within normal limits). You're going to have to come to peace with your losses and the testing isn't going to give you that what you might be looking for in your heart. However it definitely can give some small sense of peace by helping thru a process of elimination determine if there "might" have been a contributing. Sometimes there is something wrong, but easily treatable and at the same time there's no way to say that's why your previous losses happened

It's disturbing no matter what. We really don't have peace when it comes to our losses
