"i took this pills for 8 months and once i stopped taking it, acne 
suddenly became my biggest problem and half year later, i was diagnosed as pcos and my doctor told me that i had to take birth control pills again! it is really tricky that a med used for curing an illness seemed the one that also lead me to this illness( my period was very regular in the past ten years before 
i took this pills) .  i switch to other brands anyway."
