Questionable

I have only ever been with one guy. He was my first and only boyfriend who I am actually currently having casual sex with. We call it “Friend with benefits” or “F*** Buddies,” the stereotypical names for it. I had an application before this one that logged my menstrual cycle and it would tell me when I was ovulating. During that time I hadn’t started my next birth control packet and had been off of the pill for a month. We had sex multiple times during these days with no protection. It’s only been about a week since then and I haven’t started my period, being 4 days late, should I be worried?
