Any experience with Plan B???

So this weekend my bf and I were having a LOT of sex...it was the break up-to-make up type of sex because I just broke up with him last week...anyway it was intense. So intense that he came in me. I’m currently on the pill but I wasn’t confident enough that it would be effective because of how deep he was inside me when he came. Either way, he bought me a Plan B pill and I took it yesterday...

Today my boobs are tender af, my stomach is all bubbly like my period is about to come on, and I feel extremely sluggish. Has anyone else who’s taken this pill had similar symptoms?
