Ethinyl estradiol / norethindrone
"DO NOT TAKE!!! I was only on this pill (only birth control I've ever taken) and it was awful...a period every two weeks, awful cramps and mood swings, weight gain, and to top it all off A BLOOD CLOT IN MY LUNG! I don't smoke and am not over 35 (supposedly the only things that would trigger a serious reaction) so this is all the pill. I've been off of it for months and am still having issues. I have to be on a blood thinner indefinitely and live with the constant fear of a clot reaching my heart. Please DO NOT TAKE THIS PILL."
