"i got on the shot when i was 17. i&#039;m 18 now. i&#039;ve gotten it roughly 3 or 4 times. i had always had awful periods and at the time it had been four years since i had gotten my first period. initially i was scared to get the shot due to the things i had heard. i heard that it could cause weight gain, mood swings, excessive eating, and it could even result in making your period worse. once i got the shot, i had my period maybe three times after that and it lasted for about three days each time. i haven&#039;t had a period for six months which is amazing when it used to be something i struggled with often. i weighed 117 pounds when i got my first shot. i weight 114 now. at first i was a bit on edge with my attitude but it was nothing serious."
