Help me not test early

India
I'm not even out of my fertile window yet, but I'm trying to stay ahead of the game as far as my crazy brain. I have a horrible horrible habit of testing early. I do it every month even though I promise I won't. What do you ladies do to keep yourselves from testing early? It's just a letdown everytime and even when it's negative I drive myself crazy with the "it's just too early" mantra.
