Should I be worried

Idk if this is the right place to write this but on the third my bf and I had sex and when we were finished we realized the condom had a tear in it. I didn’t freak out too much because my glow chart said I only had a 3% chance of being pregnant. However I’m getting more nervous because it also said my predicted ovulation was on the 31st of January so only about 3-4 days before the incident. Do y’all think I should be worried or do y’all think I’ll be fine?
