birth control
"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'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've never been concerned about my weight until now. I know my body and implanon should not be it"
