"i use to be on gildess for years and never had a problem with it . when they discontinued  it i was prescribed blisovi. when. i first got my period i had insane headaches and thought i just needed, to adapt to the pill. my periods on gildess lasted like 3-4 days now on blisovi the last over a week and are heavy . in 2 months i have gained over 10 lbs and i workout 5-6 days a week and my breast size went up a cup. i called my physcian after reading everybody&#039;s reviews and experiencing all the negative symptoms."
