Why doesn't anyone read the Plan B box before taking it??

All I see are questions regarding side effects that are clearly outlined right there on the box....I'm reallyy not trying to start an argument or judge anyone but I really honestly truly don't understand how so many people can take an unfamiliar pill and do zero research on the effects it can have on your body. When I took Plan B for the first time over a year ago I read that thing front to back. Along with researching it a bit online, but maybe I'm just more paranoid than most people??
