"i started taking this to prevent pregnancy, since i have light, painless periods and no acne. even after a year, i had acne breakouts every month, significant cramping on my periods, loss of appetite, nausea, and mood swings/suicidal thoughts during my pms week. i decided to switch after i kept waking up in the middle of the night with severe stomach pain. i&#039;m sure it works fine for some women and it did prevent pregnancy, but the side effects weren&#039;t worth it."
