"i have had implanon for a year now. i liked it at first because i was living with my boyfriend at the time and it avoided pregnancy but after having it for a few months i gained 20 pounds! i was 110 now i&#039;m 130lbs. i want to get it removed asap and hopefully go back to my regular weight. i also experienced crazy mood swings. it&#039;s great to take if you want to avoid pregnancy and to avoid the pill and other annoying birth control but i would suggest sticking to condoms."
