maybe i’m just paranoid?

i started my period monday of two weeks ago and started my first ever pill pack the same day. my period usually lasts 5-6 days with the occasional drop of old blood. however, i believe i have spotted because it was brown blood during day 8-12, but faint. I did have protected sex with a condom 9 days after starting bc, and he pulled out before cumming. i’m on the last week of the hormonal pills before i get to the placebos, and i am a little worried that i might not start next week? is there any way to tell if i will get my period on my placebo week?
