Does anyone else feel defective?

Amy
I have been TCC for a year now. My Husband and I are suffering our second miscarriage, what did I do wrong? I've been on my vitamins for a year, I haven't drank for a year and I don't smoke or do drugs. I was so excited to see the line on my dye test. 
My doctor wants me to see a specialist.. But I am too ashamed to go right now, please tell me I'm not alone
