3 days late negative test

Hey guys first time posting here 👋🏻
So I am 3 days late from date of expected period but still getting a negative test 
Should I retry testing in a few days? 
Has anyone else been through this ??? 
Xx
UPDATE
Day 6th this morning and it came today just light flow only when I wipe 
So probably no chance I'm pregnant right ? Really thought this was my month 😪 hate when my body tricks me !
