That's right, my periods are gone for good. On birth control pills, my periods got lighter, but never stopped completely. When I first got my IUD, I did have some random light spotting, but that went away pretty quickly. This is normal for a hormonal IUD, however a non-hormonal IUD, like a copper IUD can actually make your periods longer and heavier.
I happily threw away all of my pads and tampons and don't have to walk down that dark aisle in the store anymore. Now I don't have to worry about my periods disrupting my life.
