Do I have to take Plan B again?

I just have a quick question about Plan B. And yes - I know it's not a substitute for regular birth control and I 100% understand that! So just know that before answering. If I had unprotected sex and took Plan b the following morning, and then I had unprotected sex again several days later, do I need to take Plan B again or does taking it the first time completely stop me from ovulating during this cycle? I was unable to find a clear cut answer to this question online. I'm not looking for any judgment or lectures here, I'm asking a hypothetical question because I'm curious. Thank you!
