birth control
"I have had my Implanon for 3 years and need to get it removed in a few days. I love it. I had No periods for about 1 1/2 years, then one every 4 months for a year.

The downside is now it's closer to one week long period with a week long break in between. It's been really frequent for the last month or so. 
I am about 175 lbs though, and I don't know if the tapering off would be so obvious in someone with less body mass or even more muscle mass. I am thinking about getting a new one in anyway, or perhaps taking a shot or two of Depo before getting a new Implanon inserted."
