LATE PERIOD

So my period is a day late ! 
I don't really feel like I'm going get one u know how you get the feeling when u know ur going start soon well I feel normal . 
I really don't want to get my period at all it's HORRIBLE for me .. I got my depo shot feb 2 could this be why I'm late dose anyone know if when ur ok the depo shot you will even get a period? It's either the shot working or I'm pregnant 🤷🏽‍♀️ ???
