Etonogestrel
"I originally had implanon years ago when it came out. I LOVED IT! it was great. never gained a pound, never went through any side effects and never got pregnant. When the 3 years was up, I had it removed and went on the pill because they didn't offer implanon anymore for whatever reason. In December, I had nexplanon placed. Thinking because I did so well with implanon (after my Dr told me they were exactly alike). Wrong. Between horrible weight gain, fatigue and mood swings, I'm so done. made an appt to have it taken out. CANNOT WAIT!"
