"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&#039;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&#039;m so done. made an appt to have it taken out. cannot wait!"
