It took us a while to conceive this time around with #2. In the end we were so disheartened with getting a negative result every month, we decided to give up and just get on with life. Christmas came around and with all the extra heavy drinking indulging, it just sort of happened.
Stop physically "trying".
Just concentrate on enjoying your relationship. Go out and eat nice food and have a drink. As a PP said, tracking etc just adds pressure, every time you have sex all your thinking about is baby-making. Try to have sex any time you feel like it, not just when you might be ovulating and try something new you've always fancied.
I hope it happens for you soon, I know how shitty it is to wait and wonder "when is it our turn" every month
