Period is late, testing negative

Hi ladies! Sending everyone baby dust💕

I was hoping for some insight. My period is 5-6 days late and I am getting a negative pregnancy test. I have taken one every morning since I missed my period. My period is always regular and I do feel different than normal and have had some of the pregnancy symptoms you read about online.

Is it possible to still be pregnant and get a negative test this far out? How long does HCg take to show up?

Holding onto hope! Thank you!
