This may be a dumb question but I had unprotected sex with my bf last night and he came in me. I do have the Kyleena IUD but just to be extra sure I took a plan b (within 12 hours of unprotected sex). However, when he came in me he was still in me for a couple minutes after. I wasn’t sure if I should take a plan b right away because will it be effective if there’s a possibility of his cum still being in me? Is that even possible? Or am I overthinking all this
