birth control
"I've had Implanon for 2 and a half years now. I can't wait to get it out and I will never get it again. The main reason is I have gained A LOT of weight with this, and also I feel is the cause of my acne/mood swings. My periods have now stopped completely, besides the odd month of spotting. Spotting that may last about 2 weeks, then stop for one week, then come back for another week. It definitely does it great job  as acting as a contraceptive. Handy for people who don't want to take the pill everyday."
