I've been taking Aviane for years, to help regulate my periods. Before Aviane, they were irregular (it could be a month and a half before The Dot.) and could last 5-7 days, and my mental health was terrible the week before. (PMDD)
I have terrible memory at times, but I know for a fact that Aviane has regulated my periods and has shortened them! They're now only 3 days long, if that tells you anything! I can't remember much about my first few months taking the pills, but overall, it's been helpful!
