can i get pregnant ?

i stopped my period friday, i have taken my pills but at different times for example friday i took it at 5p.m, saturday i took it at 12p.m, sunday at 3p.m and today at 10p.m. i had unprotected sex sunday around 1a.m and he used the pull out method ( ik not very smart ) but is there a chance i could become pregnant because it was 2 days after my period stopped and that i’ve taken my pills all at different times? please help
