How do I stop getting my hopes up every month??

I have an entire box full of negative pregnancy tests!!!

I’m currently a few days late for my period, kinda nauseous and crampy, tired and moody.

I always feel the same every month, but my periods are usually bang on time.

I don’t want to spend more money on tests just for it to be negative.

HOW do you stop yourself from getting your hopes up and obsessing over every little symptom. I’m about 19dpo now.

I’ve been trying for over two years, and it’s the same heartbreak every month. :(
