Ethinyl estradiol / norethindrone
"I began taking Lo Loestrin Fe in March, 2016 as a remedy for very heavy, frequently spaced periods. During the first two months I had 4-5 breakthrough bleed days. The bleeding was more than spotting and more like a regular period.  By the third month, I had no period and only a very small amount of breakthrough bleeding. I have no other side effects to report, and at this point am happy with the very light to non-existent periods and almost no breakthrough bleeding."
