I have been having prolonged menstrual symptoms. I begin with anxiety/mood swings, cramping, and nausea approximately 2 weeks before I start. I am fatigued, a metallic taste in my mouth, cramping, and mood swings during and about a week after. I also have to change my tampons/pads every hour during menstruattion on most cycles. It only lasts 4 days, but the side affects don't seem to slack off except a couple of days a month. Should I be concerned? (Four kids, four pregnancies, all normal, tubes are tied. In case it helps.)
