"i&#039;ve been on micronor for about three months now and i really have no complaints/haven&#039;t noticed any negative side effects. the only changes i&#039;ve noticed, though i&#039;m not sure if they have to do with this medication or are just from stress, but my breast size has decreased and i have almost no appetite. no complaints though! it has prevented pregnancy so far, which is why i&#039;m taking it! also, no periods or spotting to speak of."
