throwing up after birth control?! Plan B or no?

Okay so i take my pill at 8 (sometimes 9) everynight, on Saturday I took the pill a little before 8 because I was going to a party. well I got really super drunk and threw up at about 2:30 am. about 2 hours later my bf and I had sex (multiple times) but he came in me once. I've never let him do this but the sex was good asf. he asked if he should get me plan B and I was like "no I should be fine, I take the BC everynight. but if it makes you feel better I will.". I DIDN'T THINK ABOUT THE FACT I THREW UP. do you think that I'll be fine bc It had time to settle and be absorbed or should I get it anyway.?!
