I lurk up here occasionally to see how everyone (from the loss boards) is doing, although I never really posted here. I am sorry for your losses, but just wanted to let you know that you aren't alone. I conceived DS without any problems (not trying, not preventing). After him, I had 2 b/o's and like you thought the first was a fluke. I considered testing, but decided against having it done because as Heather said, I understood it to be a chromosomal defect. I got p/g again my first cycle after my last m/c and now have a beautiful DD. If you want to know more about testing, you might want to stop by the Recurrent Loss Board and someone there might be able to help as many of them have had testing done and it might give you some ideas as to what to ask your doctor about.
