Is there a high chance I could get pregnant from unprotected sex 7 days before my period?

I’m looking into all of my options. We were drunk and celebrating and I agreed to letting my husband cum inside of me. I’m not on birth control. Not sure when I ovulate, but I think I did a few days ago based on discharge. I have had one period since I gave birth in June. I know we were careless, but we planned to have children close in age so if it happens it happens. I’m just wondering if there’s really a chance.
