Ethinyl estradiol / norethindrone
"I'm 43, and I have severe endometriosis.  Every month I am in so much pain that I have to lay in a dark room all day and night with a heat pad and eating a lot of midol just to survive the day.  One doc told me I needed a hysterctomy. The second doc said I should try lo loestrin fe.  So, I tried the pill.  It took almost 4 months of irregular bleeding and a lot of painful days until it regulated itself.  Now I go months without a period! It's amazing.  Also, the second month, my boobs grew a cup size, but then they went back to normal size.  I take the pill at 9 pm every night so that I won't feel nauseated.  If you have endometriosis, this can be a game changer!  I was told I can take it until I'm 53."
