"i have been taking this pill for about 6 months, to prevent pregnancy. i&#039;ve had regularly light periods and my appetite has drastically decreased, but i haven&#039;t been losing weight. it slowed my sex drive down in the first few months of use, but my drive is back to normal now. i am also very moody, lethargic, and constipated. however, i like it since it is preventing me from getting pregnant and it&#039;s free."
