What's normal?

According to the doctor, 2 miscarriages is normal. And so, no testing. It's not until after 3 emotional wrecks that the doctors start taking a woman seriously. Easy for them to say that 2 is normal. I wonder if whoever made that rule ever experienced "just" 1, let alone 2. The doctor was as nice as possible in telling me, and almost made me feel better by telling me those types of tests usually don't give any results anyways, but it still makes me wonder. Would it be different if I had a US doctor? Maybe I AM normal, and this time around I will have no problems. I sure hope so.
