Suggest Remedy For Periods Problem

Hi, im 30 years old and have odd periods. ive been feeling nauseated, hungry, moody and have palpitations. I have known atrial flutter and comes and goes (I can feel it and become short of breath). I also know that my iron levels haven t been the best but have been taking iron supps with vitamin c daily to 2nd daily depending how constipated I get. Nexium doesn t help.
