ovarian cysts
"I am 40 years old.  My doctor prescribed this medication to treat heavy bleeding due to an ovarian cyst that developed after several Clomid cycles with my infertility specialist.  After three months, my periods are regular again, but at the cost of several unpleasant side effects.  I have painful cystic acne in my genitalia, I have gone from being calm and relaxed to short-tempered, and my sleep cycles have been disrupted, leaving me tired all the time.  The first day or two of my period is extremely painful, but that may be due to the fact that I have more like a 25 day cycle and the pill is trying to force a 28 day cycle. "
