Etonogestrel
"I was put on implanon a month ago and I was told that there might be some weight gain (like 5 pounds) or a chance of depression and irregular period for a while. Let me tell you something. They're spot on with weight gain, personality changes, and irregular period. I usually have a heavy flow without cramps. Now, I can't move without feeling like I have ebola. I'm bleeding profusely. And worst of all, the blood smells 20x worse than usual. I've gained 10 pounds, bled constantly, and my emotions are going haywire. If anyone says you won't have a period, they're right. Your vagina literally turns into a scene from Sweeney Todd. Feels like it too."
