"i was on the depo for over 9 months. its a very great birth control because you only need to get it every three months. the only thing i hated was gaining weight. i was 120 pounds when i started. i now weigh 145 and i cant seem to control the weight. i never struggled with my weight. that is why im getting off of it and i&#039;m switching to para-guard iud next week. it was a great birth control to use, and if it wasnt for the weight i gained i would have continued it. beware of the weight you will gain with depo!"
