Irritable, Poor Memory, Tunnel Vision, Cold, Heart Burn, Nausea, Lightheadedness, Loose Stools, Back Ache. What Can I Do?

A week before I start my period I get extremely agitated and irritable. Than I get a very sharp back ache on my lower back.when my flow becomes heavy I begin to feel very light headed, unable to focus poor memory and tunnel vision where I instantly and very strongly want to fall asleep. It's brief but happens often. I feel very fatigued, can't tolerate the cold very well. I will suffer from heartburn causing lots of nausea. I get loose stools the entire time I am on my period where I visit the bathroom 4 or 5 times a day just for that. When I near the end I get a migraine where I am stuck in bed sometimes for two days. Usually one full day. It's there anything I can do?
