thyroid experts

Man i'm on a roll tonight! I still haven't heard from my doc about my lab results so I was a bad girl and looked them up at work. My TSH was normal but my free T4 was low. So now i'm freaking out. I tried to google it and from what I can tell that can cause miscarriages. So if that's true I want to know because we're TTC this cycle and its a freaking holiday! Anyone have any input?
