Possibility of being pregnant

ok so I’m really nervous about this , being that’s it’s the first time this has ever happened to me. So this happened yesterday at around 3am , me and my boo had sex and he ended up coming in me. He got me a plan b and i took it around 9ish maybe 10ish pm , then we had sex again At 3am and he came in me AGAIN. Should i buy another plan b or just wait and see what happens 😭 i think the worst part of this is I’m ovulating and according to the app yesterday and today are my highest chances of getting pregnant.
