birth control
"I was on depo for 10 years. The only side effects I experienced were a complete lack of period (which I think is great) but a reduced sex drive as well. There were also concerns from my doctor that I may experience bone density loss due to extended depo use. After some thought I went with the arm implant because it seemed fairly noninvasive compared to other methods. So far so good. It's been about a month. I was told if I had a positive depo experience I should have a positive implant experience because it's the same hormone with a different delivery method. I still don't have a period ( I actually like that) but I had a bad bruise at the insertion site initially, and a month in I can still see and feel the implant and it's sensitive."
