"i have used ocella for years and have not had any major problems. the most i have felt is some breast tenderness close to my period which i have always had and sometimes some mild nausea my first 2 days or so on the pill during the first active week. i am happy with the effectiveness. i had irregular and very heavy periods that would last 11 days. this medicine has given me light and regular periods normally lasting 5 days. i haven&#039;t experienced any emotional side effects or severe physical effects."
