"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."
