Test or not test?

So it’s about that time again, where I test everyday for a positive to BD. A best friend of mine who just gave birth to her baby boy advised me to not stress and test. To just let things happen as they happen, not trying to control the situation by knowing when I ovulate. I just don’t know my nerves can let me do that! She conceived by ‘not trying’ after almost a year of trying. I know this is long. Any thoughts or advice?

This will be our 5th cycle trying, so not that long into it but have yet to get a BFP.
