Depo-Provera
"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."
