Kyleena IUD

Hi y’all! So I just got my IUD inserted yesterday!! Worst fucking 10 seconds of my life, and yeah I know, it’s still “easier than child birth” as my doctor put it. I’ll get there when I actually have a baby in like 5 years! 😂 Anyways, I’ve been reading posts about checking your IUD to make sure it’s still in place, but I have no idea what the “string” is supposed to feel like! Can someone explain what it feels like and exactly how to check it? Thanks 🥰
