Plz help...

I am on birth control but I had sex without a condom (for the first time) when I was on my placebo pills .. my birth control is still a few months new and so my period isn’t lined up with my placebo pills yet... I was supposed to get my period 5 days ago (according to my app) but it’s been 23 days since my last period.. I’m just nervous. Is there any chance I could be pregnant ?? Since I wasn’t technically taking the pill when I had sex
