"at 26yrs i was 68kg when i had my implanon inserted in july 2014. september 2016 and i am 82kg. i have gained 14kg in 2 years + 2 months. i have not changed my eating habits much,  if anything i am more active and constantly on my feet. i have always been a size 10 girl and to suddenly catapult to a size 14 in a matter of 2 years is ridiculous!. i truly believe it is the implanon effect and i am having it removed next week hooray!. i have tried exercising and reducing my daily intake to lose weight and sadly lost no weight. it&#039;s so frustrating that doctors would laugh at me and say i was overeating or lack of exercise. i was a track athlete and i&#039;ve never been concerned about my weight until now. i know my body and implanon should not be it"
