PLEASE HELP

Please help me. my bf and i had sex this morning, i had an 11% chance of pregnancy and 4 days away from ovulation. the condom broke, we stopped, and he didn’t finish inside me. i also took plan b an hour and a half after we stopped. is there a chance i could be pregnant? did i take it soon enough? please help me. i’ve been having panic attacks and breaking down a lot. my parents would kick me out if they found out. please help me..
