"i haven&#039;t had big issues with this pill. i was on junel fe, but my pharmacy switched it back in early february or march of this year. i haven&#039;t really seen issues with this brand. i used to have really heavy periods, but now with microgestin, they are really, really light. my last period was the lightest i had ever seen it, which makes me worry, but reading other comments i feel better. everyone is different. i haven&#039;t had any weight gain or breast enlargements. i love the fact that i start my period every month on the same day, tuesdays, (or sometimes mondays). it usually lasts 3-4 days. the only &quot;trouble&quot; with this pill is the lightness of my period."
