No breakthrough bleeding?

im on the pill so usually when I try to skip my period, I still have bleeding anyways. so last month I got my period on wednesday (4 days into the placebo pills) like normal, so I started my new pack thursday to

try and shorten my period it didn’t work.. this month I had unprotected sex, but he didn’t finish. so I started my new pack the week of my placebo pills to try to skip my period and then today (the day my period would usually start) I half-heartedly didn’t expect it to because I had started a new pack but I kinda did expect it to happen because I usually still bleed anyways.. but i haven’t had any bleeding.. Should I be worried about being pregnant or maybe it’s just finally working and I don’t have breakthrough bleeding this time? I have had some strong cramps too
