"i have been on the depo shot since april 2010. i actually got it the day after giving birth to my daughter. i&#039;ve been spotting for a year now (and still is) i&#039;ve gained at least 30lbs, i have no sex drive, and i have lost about 3 inches of my hair. the only good thing is it does prevent pregnancy but that&#039;s about it. definitely switching to something else."
