Yikes, I can’t imagine who would recommend copper unless someone had a bad reaction to the hormonal type. The mode of action is totally different, with hormonal suppressing the whole cycle and copper being more like a continuous abortion.

My wife didn’t have a period for years aside from some occasional spotting with Mirena, I figure if we can save my daughter a decade of cramping and bleeding by offering her one young, the birth control is almost a happy side effect.
