"i started bc when i was 15 for acne and i was on ortho tri-cyclen lo for about a year. i woke up every morning sick to my stomach, i had no appetite most days, and my acne only sort of improved. my insurance switched and so i switched bc to bc for a few months straight. i went from a knockoff, to sprintec, to knockoff of that etc. all helped with the nausea a little more, not too much with my acne, and a few made me very depressed. i switched to previfem and i have been on it continuously for around 2 years now. it makes me feel so normal that the first few weeks on it i was scared it wasn&#039;t working. not pregnant. no acne. i have my cycle down to the exact hour. would recommend for young girls who don&#039;t react well to combo packs."
