"i had terrible pms on this pill.  my cramps and back pain were unbearable, even though it didn&#039;t last long.  i could have eaten 10000 lbs of chocolate during pms as well.  i was on my period for about two weeks a month while i took this.  i would start in week 3 and bleed very heavy for 5 days, then light and thick for the next 9 days.  i had to get off.  i did not experience mood swings on it though, that was the good thing...but about the only good thing."
