Plan B

I had sex day before yesterday and the guy got off in me 😳ekkkkk. I don't take any type of birth control because I didn't think I would give in. The next day within the 24 hours I took plan B. Well the guy came back over last night and I thought I could remain strong and I failed. He got off in me again TWICE. I had told him not to. And he did it without me knowing. I know. I'm so stupid. 
My question is... Do I need to take plan B again????????
