"this birth control took some time for my body to adjust. i asked to be switched to a lower estrogen birth control because my previous birth control that i was on for over two years was making me feel more and more crazy the longer i was on it. it took a solid three months for my periods to regulate, but since then they&#039;re really light (almost don&#039;t even need to wear a tampon) and little to no cramps. my mood has significantly improved. the only downside is i gained 13 pounds the first three months of taking this birth control."
