"i&#039;m twenty years old and i&#039;ve been on this birth control for over two years and have never had a problem with it. i&#039;ve always had irregular periods and when i did have them i was in immense pain, but since i&#039;ve been on the depo shot i haven&#039;t had any spotting or a period and it&#039;s wonderful. first week or so i had mood swings but that was all. a+ in my book! also, i haven&#039;t had any bone density issues."
