What Do Y'all Think?

I've already set it as late for today, but there are 3 more days in this month and I'm not sure if I should test or not. 
I've always had weird periods, but never been this late. I was suppose start 2-3 days ago. 
I usually have my period 7 days, do you think it's possible I'll start in the next few days and go almost a week into July on my period or should I just test??  
Sorry if this sounds silly. This is my first time to post!!!! Thanks for any tips ☺️☺️
