Etonogestrel
"My first implant went extremely well. I got it put in during my period, which is usually heavy. The next time I had it the flow was noticeably less. After when they would come it slowed till it eventually stopped. I went 2 years period free but when it got close to the time to take it out my period was radically crazy. I would spot then stop the next day or get a heavy flow then the next week spot again. I noticed even before these symptoms that I would get a slight shock or ache where the implant was put but to me this was fine. I got it taken out and was off it for a year before getting another. This time my period is now hitting its two weeks. So I'm going to switch to depo to see if that works better. They say to switching BC helps."
