Missed pill

On vacation this week for my birthday and I forgot my pills 😩 with a couple nights going out getting drunk my boyfriend and I stupidly and foolishly had unprotected sex 🙍. It's day 17 of my cycle. I'm home now took today's and yesterday's pill. Should I get plan b? Should I take the remaining other pills? Please help and please no rude comments I know I should have been more careful thank you.
