endometriosis
"I was put on this medication because I suffer from endometriosis related pain as well as extremely irregular periods (I had about 3-5 periods a year versus once a month). I can happily say that I no longer double over in pain, it's still uncomfortable but not unbearable, my periods are also much more consistent. However, I have noticed mood swings that I have never had a problem with before, as well as more than normal breakouts (mostly around my chin and cheeks). I also experienced a bit of nausea the first couple months I was taking it, eating right before you take it helps a lot. Overall it did what my doctor and I set out to initially do, but it does have some side effects i'm not thrilled about."
