I took two plan b pills in a 24 hour period

well first before I start I wanted to say i’m not on birth control because i haven’t been sexually active in over two years. So I had sex with this guy i was talking to on a thursday night and he came in me. so i took a plan b on friday evening. we hung out late friday night and we also had sex that night. So i took another plan b on saturday afternoon. i’m 99.9% sure I was ovulating. my question is, what are my chances of pregnancy? Have any of you ladies ever been through anything like this? In my defense I told him not to finish in me and he did anyway, and he claims he is sterile and can’t have kids. But i am still worried. i just feel like i have no one to talk to about this. Thank you :relaxed:
