Help me pleaaase

I came off the mini pill around September/November last year and I know that my periods can be a little different every month but since I have been on glow my periods have either come on the day glow says it will or a day early or a day late but this time I'm four days late! Should I test or wait and see? I just wanna know if I have a bubba in there or not!!!!🙊🙊🙊
