Should I get my hopes up?

My period usually lasts 7 days and I have 18-19 days til the next one starts. My last period only lasted six days and it’s been 23 days since my last period meaning I should be 4-5 days late. Glow says I’m only 1 day late.

So I took 3 tests yesterday which all came back negative. Am I wrong to still have hope? Should I test again or just wait?
