pill/period question - helpppp

i’ve been on tri-sprintec for nearly 2 years now. last month, i started letting my boyfriend not use condoms when we have sex. he’s been pulling out and not finishing in me.

i took 2 out of the 7 placebo pills on my last pack and then started a new pack while i was on my withdrawal bleeding.

i’m about to start my placebo pills tomorrow. i have not missed a pill this month and have been taking my pills within 5 minutes of my normal time everyday.

should i be worried ??? my chances of pregnancy would not be high correct ??
