Missed period

I’m 20 years old and I have two apps that say my my period is late , one says it’s 3 days late and the other one says 2 days late . I don’t know what I should do . Should I go ahead and take a test or wait another week to see if my period comes on . I need advice on what I should do cause I’m scared that I may be pregnant but i haven’t been having any signs that I may be pregnant.
