"started this birth control at 15, light periods/spotting for about a year. i&#039;ve now been on it for about 3 1/2 years only reason i&#039;m stopping is because it was recommended by my doctor to start nexplanon. i didn&#039;t gain any weight for the first 1 1/2-2 years but, i did gain about 35-40 pounds which could of been from the depo or just puberty. if i could stay on it i would but it&#039;s not recommend to be on more than two years because of calcium loss in some people. wish me luck with nexplanon! i hope i don&#039;t get my period with it!"
