"i&#039;ve had implanon for about4 years now. i just got it reimplanted. if i recall correctly you do spot the first year or the first two years. i just don&#039;t remember spotting as much the third year. your mood may change a bit. you may get some acne. you also may gain some weight. i don&#039;t know how it affects my sex drive. this is what i&#039;ve experienced. however, in comparison to other birth controls, this one is great. the bloating and backache that i got when i was on my period is nothing compared to the small bloating and backache you may get when on this. i get no cramps or fatigue. depo provera gave me hot flashes. the nuvaring kept falling out."
