I have being taking a low dose of Norethisterone daily for 25 days, but it has exacerbated all of my pms symptoms, including headache, migraine, stomach upset,72 hour colds, constipation, mood swings, night flashes, poor sleep etc I have now stopped it. I am awaiting a hysterectomy due to fibroids but think I may be menopausal so am not sure this is the best solution. Is there an alternative to this medication?
