"as far as birth control effectiveness goes, it does great. never had any issues with that. however, the mood swings/anxiety/depression were terrible. and they&#039;ve only gotten worse since i&#039;ve gotten off of it. it&#039;s enough that it&#039;s severely effecting my outlook on life and my relationships with those around me. i&#039;ve recently become active and notice it&#039;s easier for me to get hurt than it was before. (i assume that&#039;s because of the bone density loss..) i was on this for 9 mo/3 shot cycles and i never adjusted. it may work for you, but it did not for me. i&#039;m going to try an iud next and hope for better results. fingers crossed."
