Ethinyl estradiol / norethindrone
"I've been using Lo Loestrin Fe for almost 10 months now I began using them after I gave birth. They are truly effective I don't suffer from spotting or periods and I don't have to worry about getting pregnant. My doctor did mention with drinking this your stopping your period if you have periods, you are probably taking it wrong. It's normal to spot a little on the last week of the pack."
