Ethinyl estradiol / norethindrone
"I've been on this birth control for severe chronic pain due to endometriosis. I have been taking it for about 9 months continuously with no placebo. I have not had a period since taking it which makes the pain a lot more bearable. I have gained about 10-15lbs. Major sweet tooth that I didn't have before. My breasts are also bigger. In all I'd definitely recommend this pill for endometriosis pain. My chronic pain is still there, but wayyy more manageable! I plan to stay on this pill, skipping periods as long as my doctor allows. It's the only thing that has lessened the pain."
