"i have had this birth control since april of 2012; having it changed last year. i have my own bouts of anxiety and depression so that may contribute to some of my issues. but i can say that; i have gained a lot of weight since being on this birth control; even when i was walking 10 miles a day and barely eating i only lost like 15 pounds at most; i started off at 155 with this implant after having my son. once i started being more active i made it to 140; now, after just 4 months of not walking 10 miles a day but still being active i am up to 171 lbs. it&#039;s ridiculous. i plan on having the copper iud inserted soon. i also have trouble with breaking out a lot, mood swings, and a non-existent sex drive."
