Feeling disheartened :(

Been trying to conceive for nearly 1 yr and am slowly losing hope each month. I have been timing each cycle with opk and have started with a  fertility monitor and started temping a few cycles back and still nothing. Thought I was pregnant in December but it was a chemical pregnancy, nothing like getting your hopes up. Sorry for rant but am slowly losing my optimism. Anyone out there with some advice or inspirational story??
