"I got switched to this because I get auras with my migraines.  It gave me menstrual migraines, and periods every other week. My periods were heavier, longer and a lot more painful.  I don't really have PMS, but on this drug, I get mood swings, painful constipation, acne and a sore genital tract.  The menstrual migraines went away after three months, the first month the period pain went away.  

Over the course of 18 months, my vaginal discharge disappeared.  It made sex so painful that it's impossible.  It also cause stress incontinence.  I've been off it for six months and the lack of discharge still a problem because I'm apparently not allowed to have any type of estrogen."
