"i have been using this birth control for over a year, and it has proven to be perfect. the first 3 weeks i was taking it, i had pretty bad mood swings, but this is expected, and they quit happening around the time i started my second cycle of pills. i had irregular periods and bar cramping; both of those problems were fixed once again by the second month of pills. my flow was much lighter for a shorter amount of days (and you still have a period every month, which allows your body to still clean itself out). as a contraceptive, it is my only method of birth control and i&#039;m not pregnant yet, so it&#039;s doing its job there. never had acne but i break out less often. basically this is a great pill."
