"i was on microgestin fe for about 2 years . even in the beginning i never had any bad/abnormal side effects. with it i experienced a small amount of weight gain, tender breast every month around my cycle, increase in my breast size,  and my monthly periods lasting 2-4 days with minimal cramping. the only reason i switched was because i wanted less periods. (i switched to amethia-lo and i&#039;ve been on it for about a week now. i hoping it works well with me but if not, i&#039;ll definitely switched back to microgestin fe)."
