"i always had trouble finding the right birth control for years now. not only would certain ones contribute to a lot of weight gain or very bad mood swings, i was horrible with taking my birth control pill on time. i was having horrible cramping and pain with my periods to the point that i would have to call off from work! since being on the depo shot, i have had no side effects. i always eat a lot and i don&#039;t work out often so if i do gain weight, that&#039;s my own personal issue. i&#039;m glad to read these reviews and to be informed about the bone density because my doctor clearly never told me that. i haven&#039;t had any mood swings or emotional break-downs like the other pills did to me!"
