"i started taking aviane because of horrible pms while on mircette and did the three month continuous route. it kind of helped alleviate pms but for some reason my body wouldn&#039;t listen to the pill and continued to have a monthly period well into the second three month span along with spotting. the breaking point was when i had a total pms episode complete with migraine and heavy period about a month and a half into the second three months. i am switching to yaz, and hoping things improve!"
