What do I do

So according to my app I’m suppose to start my period on Sunday. 2 days ago I thought I was spotting it was a light brown color then it stopped for a day and then today it was very faint again today. Usually if this happens before my period I’m cramping and feel off but I feel completely fine. Im a little confused on what I should do. Should I wait until Sunday to see if my period show up? Help me 😂
