New to birth control need advise

Hi! So I started taking the pill in oct of 2020 ive always been on time with my pill, only late 3 times in the beginning because u was getting use to it.. nothing after. And in July my bf and I hooked up and he came in me. I started mt period during the time he came to visit (long distance ) but it was only for 2 days and it was done. But anytime we had sex he came in me. I was on thr last row of pills. Should I be worried ? Keep in mind the trip was from July 11 to the 16 (sun to Friday)

Side note: the app does say im suppose to start my period in 3 days
