"i am 21 years old was placed on this medicine for having high blood pressure and it being an estrogen free birth control. i was terrified or weight gain, spotting, and mood swings, all of which this shot is rumored to do. i have experience absolutely no bleeding since my first shot, got the second shot today and no weight gain (i do exercise daily). i have been somewhat emotional around the time of my normal period, but no more then usual. overall i love the shot and having no period is a plus all around!"
