"i started taking this since i was 17, 19 now. works great, but definitely gained weight. i gained about 30 pounds while on it. my boobs went from a b to a c &amp; usually they usually get tender the week before i start my period. my period lasts about 4 days with light bleeding. never had an issue with headaches or severe cramps. i took this pill every morning, but if you take it without breakfast you tend to feel a little nauseas."
