Late period, negative pregnancy test

Daphny

My period never been so late, it’s 5 days late, I took a clear blue digital on the day it was due and it was negative and took another one today and still says not pregnant. Anyone else experienced this? Should I wait a couple/few more days to test again or should I try and not worry about it? Should I go to the doctor? 😖 Help! 👋🏾
