"i&#039;m on my second implanon,  and i love it.  the first one i got i didn&#039;t have a period for the whole 3 years i had it,  some weight gain but nothing extreme. no mood swings or anything like that. i got it put in because my cramps were excruciating and my periods were irregular as ever.  as soon as i got the first one out i got another put in. this one has been different then my first. i have my period every other month almost sometimes longer then that and they last about a week but not heavy. still no babies tho! i would absolutely recommend the implanon! don&#039;t have to worry about taking a pill every day or going in to get a shot. you can&#039;t even tell its in your arm and it doesn&#039;t hurt to get put in.
