"been on this bc for a year and a half. this was the first bc i&#039;ve ever taken, i&#039;m 22 and it works really well for me. i never had a regular period , and this gave me a period the first week of every month, like clockwork.  no nausea , vomiting , diarrhea, or mood swings. no pregnancy scare  ever ( i take it the same time every day) the only thing is i&#039;ve gained about 10 pounds within this last year, but not sure if it&#039;s because of bc."
