Plan b I’m so nervous

Fuck me god help me/

I had unprotected sex for the first time on Wednesday been in a seven year relationship. Took plan b 11 hours later. I just came off birth control June 10. And I only have one tube and ovary from a surgery in November. I really don’t think I’m pregnant but still WHAT IF. Fuck me. My only saving grace was plan B. He said I shouldn’t freak out and he didn’t come in me and he’s right I saw all the shit in his hands!!! But I still took it. I’m freaking out reealllly bad
