"I am 16 years old and started the pill 4-5 months ago. Wasn&#039;t sexually active on the pill. Took some time but It cleared my skin up wonderfully. Although, I&#039;ve gained a significant amount of weight. Grew out of mostly all my jeans. I gained about 10 pounds so I&#039;m switching to another birth control. Not positive if this all caused by the pill, but weight has never been a problem for me. Didn&#039;t notice any mood changes. My periods were really light. Just not happy about the weight gain..."
