Birth control

Hi everyone I recently had sex on Monday and I was supposed to get my period yesterday on friday Nov 10. It’s currently Saturday and I haven’t gotten it but I’m on birth control should I be worried I take my pill daily, is it because maybe stress or the fact that I recently had sex interfere with my period coming late? Also I recently had cramps on Thursday to which I assumed my period was almost coming but nothing yet 😭 I am currently taking fluconazole as well due to yeast infection has this ever occurred to anyone
