"i&#039;ve had this birth control for about 8 months now and ever since then my mood swings and anxiety level are terrible. i want to eat constantly. i&#039;ve gained roughly 30 pounds or more in this period of time. i have back aches once a month when my period should be here. the plus side is i do not have a period and have not gotten prego but the weight gain is awful and i was told that it wasn&#039;t normal on this to gain a lot of weight."
