Period 5 days late, why?!?

Hello, this is my first post on here and I really need some answers/advice. My period was supposed to start 5 days ago (July 9th). I’m really not sure why it’s late because I track it on here and if anything it’s early by a 1 day or 2. I last had sex on May 27th (it was condom protected) and I even had a period mid-June. Idk what’s going on y’all. Thoughts?
