"i began taking ortho tri-cyclen lo when i was 13, i am now 22. i was not sexually active at the time, but my periods were extremely irregular. this specific oral contraceptive helped to regulate my period and it has been perfect for the past 9 years. when reading these reviews, ladies must keep in mind that everyone is different. genetics plays a huge role in whether you get/ have bad acne, cramping, low sex drive, etc. it may not be because of the pill, necessarily. in my 9 year experience with this particular product, i have never had a scare when i took the pill as directed. you will have a few of those symptoms, its just life.
