continuously trying

I need some good news and cheering up about this trying process. It's month five and still nothing. To top it off I was so convinced that I may actually be pregnant that I bought a test. I was feeling those symptoms you sometimes see, but turns out it was pms and my period just came a bit early this month. I've been tracking and steering clear of caffeine, alcohol, trying to eat more healthy. What else can I do to get this process to actually work next time?
