"i was switched to zarah for my pcos and was really happy to try something new. i had taken lutera for three years for heavy and painful periods and then for the past 6 months had not gotten a period, which is common with pcos. my doctor recommended i try zarah. just in the first month, i was way more moody and retaining a lot of water weight. then my periods came. it was the worst period i&#039;ve had since i started birth control. painful cramps and heavy bleeding to the point i needed to change a super plus tampon every hour. i am going back to the doctor to get this changed, since i waited the three months to see if anything would change. the only positive was that it was an effective birth control."
