"i have been on implanon for what will be 3 years in october. at first, i thought it was the best thing ever. i didn&#039;t have a period for almost 6 months, but once that 6 months ended, it was a never-ending cycle of my period. i am not exaggerating when i say i was on my period for almost 2 years before it started to regulate out again. yes, it is a awesome birth control but it will speak for itself. i am just now starting to regulate out. my periods usually last about 2 or 3 weeks and then i&#039;ll be off for about 2 or 3 weeks. also, over the past 2 years, its made my body think i was pregnant. which includes all the pregnancy side effects. but if you really do not want to have children, i do recommend this."
