Should I take a plan b?

Jamie

I accidentally skipped 2 birth control pills in a row but took them both immediately when I remembered, yesterday around 5pm. I remembered to take my one for last night at my scheduled 11pm. I got drunk and had sex and he came in my last night. I’m supposed to start my period in 4 days. Should I take a Plan B just to be safe or should I be okay even though I missed 2 scheduled pills but still took them? I do not want to get pregnant.
