"I was on Depo for 9 months, and overall I would rate it poorly. After my first shot, things seemed to be going normal - I was not having abnormal bleeding, I was not gaining weight (although I should say I would go out frequently and eat well), and only had a few of the minor side effects such as tender breasts. However, after the first month, everything went downhill from there! I started spotting everyday, all day long. I received two more shots to try to get my body acclimated to the hormone, and finally switched back to the pill. I also experienced a decrease in sex drive."
