birth control
"I just hit the 1 year mark taking the depo shot and decided to get off of it for multiple reasons. I was bleeding the first 3 months straight  I was on it but they assured me it would go away and it did. I has mood swings like no other but the biggest turn off for me was the weight gain. I gain 31lbs over a year time frame WHILE going to the gym 3-4 times a week and eating healthy. I thought something was wrong and so did my primary doctor so he did blood work on me an i'm as healthy as a horse! He mentioned my birth control and it all made so much sense. My friend and I started it around the same time and she was 123lbs, a year later she gained 36lbs and almost weighs 160lbs. I also lost my sex drive."
