What are your thoughts?

I've heard sooo many people say "all you have to do is stop trying and it will happen"... After TTC for 13 months how do you just "stop trying" or stop thinking about your fertile window or stop "planning" the days you should have intercourse each month? It's really hard to just not think about it!!
