"i got implanon about 2 to 3 years ago and it was the worst thing i&#039;ve ever experienced. i had it in for a little over six months and i bled the entire time, i cramped, i got migraines, so i took it out. so now i have nexplanon and it&#039;s been about 2 months. i bled for two or three weeks and then i haven&#039;t gotten my period since i actually feel a lot better. the first time with implanon my head felt fuzzy and it was hard to concentrate but not with nexplanon. i think the experience depends on your age and your hormone levels and if you had a break for a baby or not. i would have to say i like both better then the pill or patch."
