abnormal uterine bleeding
"I went on this because I am 36 and premenopausal with premature ovarian failure. My periods are 21 to 28 days apart with premenstrual migraine with vertigo and I've had severe endometriosis with removal of an ovary and fallopian tube. I've been on 5mg of Norithindrone everyday for the past 4 months. Side effects I've had: nausea, breast tenderness and cramping at certain times of the month, headaches, weight gain (12 pounds in 4 months!) -I am hungry ALL the time! Big time Bloating!, mood swings, constipation. I have not gotten my period in 4 months. Night sweats are gone. And premenstrual migraine with vertigo has decreased slightly. I still think I have been ovulating and cycling only without my period (if that makes sense)."
