Ethinyl estradiol / norethindrone
"I have been taking birth control on and off for 10 years. For the last 5 years, I was on Yaz (which worked wonders for me, I loved Yaz), but came off of them. After a year of taking no pill, I decided to give Lo Esterin Fe a chance, and my body has never acted so poorly to a birth control pill. I have never experienced any of the symptoms I am about to describe on any other birth control pill. You have to take the pill on Sunday, 4 days after starting the pill, I woke up 4 consecutive nights with piercing pains in my stomach, and a severe migraine. On the third day of pain, I started bleeding heavy, and 4 days later I am still bleeding, am in tremendous pain, and decided to discontinue Loesterin Fe. I literally stopped this pill 9 days into it."
