Confused?

I took a test Wednesday morning and it had a very very very faint line figured Id give it a few days and test again also figuring that when I did test again it would be slightly darker...... Took a test today and it's negative no faint line no nothing...AF was expected yesterday and I never started I  knew better then to get my hopes up and get excited and now I feel crushed.... Should I wait and test again in a few days if AF doesn't come
