Endometriosis
"This drug did not work for me as I am unable to take any hormones. I managed to take it for 8 weeks before stopping. I started getting a period after about week 6 and it continued on and off right up until I stopped taking the drug. When I started getting my period I still had the same symptoms (severe cramping, back pain, exhaustion, etc) that I started taking the drug for to begin with."
