Scared of pregnancy

Please no judgement lol , but I tried to plan sex not on my fertile days so it was a guess. My cycle is 29 days I believe my period ended about three days ago. I had sex on the 16th with a condom and he pulled out , I went to look on my app and it said “7% chance of pregnancy” and now I’m scared . He didn’t cum it would be been pre cum and not breaks as far as we know .
