birth control
"I had Implanon for just about two years. The first 17 months was awesome, no bleeding (at all), & no cramps. Right at 18months I started having irregular bleeding/spotting almost every week. It wasn't bad, but it got pretty annoying. I just had it removed today, and switched back to Trinessa. I gained only around eight pounds (which was a lot for me because I have always been petite). My face was constantly broke out!"
