"i have been on the depo for 6 1/2 years. i love it! it works. and no periods. no weight issues. no crazyness. about a week before i am due for my three month shot i will spot but it is no big deal. my doctor has recommended that i switch to a different birth control since i have been on this for so long and there is debate about bone mass being impacted after long term use. i am sad to switch honestly. i will be switching to mirena and am very nervous to try something different. i am only 22 so hopefully my body will adapt to mirena alright."
