"i have the implanon 3 years in january 2012. i had my period for 5 months after i got it in, now i get them every month and a half for 2 weeks but they are not really heavy. i put on 3 stone, i&#039;m depressed, i always get mood-swings, i cry for nothing sometimes. i have a very low sex drive and i&#039;m only 20. the only reason i have kept it is because i don&#039;t have to worry about getting pregnant as when i was on the pill. i always forgot to take it. i&#039;m thinking of getting it out but don&#039;t want to go back on the pill. everyone is different though, i know a girl who has the implanon and she gets no periods and never puts on weight and gets no mood swings and has a good sex drive!
