Should i be concerned?

So I have been on birth control for around 7 years now and have never missed a period. I take it everyday with a couple hours late occasionally. I was due for my period on Jan. 15th but it never came. I had sex with my bf on Jan. 12th but used protection and the condom did not break. I dont think I could be pregnant but i’m just confused because I never skipped a period before. Any advice?!
