Worried Kyleena IUD has expired, should I take plan b?

Hi so I have the Kyleena IUD and got it inserted on Dec 22,2020, and my partner did pull out during sex but I’m still nervous because of pre-cum and other possible factors since we happen unprotected sex a for a few rounds . I’m unsure if my Kyleena IUD is still effective because it’s now Jan 11, 2025 and so technically past the 5 year mark I think, should I take plan B? Is it going to negatively impact my IUD if my IUD still happens to be effective?
