"i received the implant august of 2013 and i didn&#039;t have any problems with it for the first few months then my periods were super long (2-3 weeks some times) and i started gaining weight 6 months later after no diet change or change in exercise i am now 30 pounds heavier and been insecure about my body which is really messing up my sex life. i will try and wait until the year is up but if i continue gaining all this unexplained weight i&#039;m going back on the pill."
