sex day after ovulation ?

so my period is kind of irregular i once went 62 days without having a period. i had sex the day after my "ovulation" day and we used protection the first time. in the second round he was completely leaned off and we used pull out method so idk if i should be worried. im a natural worrier and my period "comes" in 8 days. what are my chances of actually getting pregnant day after ovulation.
