"i was on yaz before and did just fine on it. they switched me to ocella four months ago and said that it was the same but i am having such a hard time on it. i bleed heavy, cramp and have migraines for at least 10 days. it knocks me off my feet to where all i can do is stay in bed all day. i have to use double protection when on my period. i bleed so much the first month that i almost had my husband take me to the er. i instead started taking iron pills to help me recover from my period. with all the scare on blood clots in the news i just called and asked my doctor to switch me to something else. the other thing was that i have zero sex drive and i can&#039;t lose weight."
