super confused and still learning cam someone help please?😊

so my DH and I had sex last night and i'm in my fertile days but today is ovulation day and i can most definitely tell because every time i wipe i get heavy raw egg white CM the thing is my husband is working out of town and idk if he's coming home tonight how are the chances of me getting pregnant by having sex last night and not on the actual day i'm ovulating (today) ??
