Accuracy of pregnancy stats on IUD

Eliza ❤

How accurate do you think those stats about the chances of getting pregnant on an IUD are? Every time I look around there are stories about women getting pregnant on them (so IUD failing). Like so many stories. Maybe it just seems that way because I have an IUD so I'm more prone to notice stories about them failing. Idk just curious 🤔🤔🤔.

I mean I know nothing is 100% effective so there's that.
