"i was originally on microgestin fe 1/20 using it for my period and birth control, i had very few cramps and very light bleeding with no side effects. i turned 19 and lost my health insurance and can no longer afford it, so i went to the health dept. and they put me in orsythia, i was told it is the same thing. i have been on this medication for a month now and i have only had headaches and extreme tiredness, some problems being mad for no reason. i haven&#039;t started my period yet but i am only on the first inactive pill so we will see. will update soon."
