On The Pill & Idk what to do

I have been on the pill (Estarylla) for about 3 almost 4 months now. I am okay with taking my pill every day but yesterday (3/28/22) i forgot to pack my pills & i was at work all day & didn’t take it until 8 hours after the time i was supposed to take it. The same night i did have sex & he did cum in me twice, im debating if my birth control will take place or if i should get a plan B? I don’t want to get a plan B but im scared i may get pregnant if i don’t do anything. im relying on my birth control but i don’t know. What are y’all’s thoughts?
