Etonogestrel
"So I've seen quite a few negative comments on here which is a shame so many people are having negative experiences. Mine however has been great! I've had mine for almost three years and am planning on getting another updated when my three years come. The first year/year and a half I would have a period which was mostly only spotting once every three months just for a couple of days which was really nice and then I just stopped getting a period at all I haven't had one in months which is amazing. And it has been working very effectively for me. I do get mood swings periodically but nothing bad and it is well worth it. I highly recommend this method!"
