I’m really scared

Me and boyfriend has sex on the second of this month. We didn’t use protection, but we did use the withdrawal/ pull out method. My hymen did break, but I still feel normal. I’m just scared I ruined my own life because what if I actually am pregnant? I don’t feel any symptoms of pregnancy, but that doesn’t necessarily mean anything. It’s was at the end my fertile window, I checked and it was at 3% chance. Can someone please help me out?
