Talk to Gynecologist on Pregnancy Information

Hi .I just got married 2months ago ,i dont have any gynaecologist right now .I want to know about pregnancy as I don’t have any information about it .is it possible if during ovulation days u have unprotected sex and later you get periods on time ,can u still be pregnant ? Can u have periods after fertilisation ? Me and my husband had unprotected sex after 6,7 days of my periods Last month I don’t know if he discharged outside completely on time or not last but then I got my periods this month it ended almost 5 days ago it was fr 6,7 days.
