menstrual disorders
"I have never been on any other birth control apart from Loestrin.  Its been about 6-7 years and I absolutely love it.  Very very light to no periods at all, no cramps, no weight gain, everything was perfect.  It has been just the past few months that I have experienced any problems.  I have gained about 15 lbs since first taking this medicine so I believe that is the cause of the change.  I am now having cramps, heavier periods and my skin is breaking out."
