He ejaculated inside me

My bf was fasting the entire month of April. We recently had sex and he ejaculated inside me now I’m scared because a lot of sperm got inside me to the point where it was leaking out my vagina abs still leaking out the next day. I took a plan b after 24hrs. Should I be worried? Not sure if I was ovulating the app says my fertility window was on day 1. Help a girl out!
