Could I get pregnant

Hi I’m 16 and I had sex for the first time today. We used a condom but it broke and he came in me. My glow app tells me there is a 7.4% chance of pregnancy and I am supposed to ovulate in 8 days and my fertile window starts in 2 days on June 1st. Right after the incident we went and got plan b and I have already taken that. What are the chances that I can still get pregnant? Please don’t leave judgement and tell me that I need to go on birth control because my mom won’t let me
