Opinions

So my bf and I were arguing, well I have the nuva ring and last night he came over to talk about our relationship. Well we started arguing again and instead of leaving and cutting me off, he started kissing me and well one thing lead to another. But I forgot to tell him that I took my birth control out....he normally asks me to make sure we’re on the same page. But in the heat of the moment he didn’t and we didn’t use a condom. I’m scared that I might get pregnant, neither of us our ready. What should I do?

Update: so the bf and I talked about it and earlier this morning he brought me a plan b, thank you everyone for your comments. He and I decided that we were gonna wait until I was a little older to try and start having our own family.
