Drospirenone / ethinyl estradiol / levomefolate calcium
"It took almost 8 months but it finally started to work.  My periods were so heavy I would go thru a tampax ultra in less than an hour and have to stay home during my periods. I would have to get up several times during the night. I would bleed some months for 30  days even on the Beyaz.  My last two months I have bleed less than three days and can use a lite tampax it took a while but I am so happy I stuck with it.  No weight gain either!!!!"
