Can we women gets pregnant if we had sex right the next day ofour period

Lovely

I have had unprotected sex many times in July on my ovulation days. My period for August must starts by 9 but I was late and got on 15 August till 20. And we starts the unprotected sex the next day. So can we get pregnant if we starts having sex right after my period ends? For this month, I would be ovulating on 31,(the next day) and we're still continuing our sex. We stop our sex during my period.
