Why do I so rarely see stories of people accidentally having a baby while happily using good birth control?

I get it, accidents* happen. And boy do I love reading all the lovely stories on this sub of happy surprises. <br><br>But I can't totally shake the feeling that birth control is designed to work so well that the vast majority of 'whoops' stories on this board probably involve a level of choice.<br><br>Which leads me to my question: where are all the stories of people who were using good birth control that actually failed, with no lapses in use or planning?<br><br>I've worked in reproductive health for years and I've never even heard of someone getting pregnant off of a Mirena or Nexaplinon regimen. Similarly, I know several people on Tri-cyclen Lo and other forms of the pill who have used it continuously for decades with no failures. <br><br>Has anyone here had birth control fail them without a fault? Do you know someone who has? I want to hear about it.
