Depressed

Tina
My husband and I have been TTC for about 2 years! The first year I understood because I had just come off getting the depo shot! But now I don't understand why it's just not happening. I've been to the doctor and everything checks out on me perfect. I want my husband to go and get checked but anytime I bring it up he gets upset and defensive. I understand that it might make him feel like a failure or less of a man but I don't know how many more time I can go getting my hopes up. It's like being slapped in the face! I get more and more depressed with each period that starts! Any suggestions on how to deal or what to do?
