I am a 21 yea old female. Right now I am having extreme pain associtaed with my period which is early. I had sudden onset of blood flow, which is unusal as I usually spot beforehand. The pin is so great I had to leave work early becaus e I could not stand. Also the past few days my head has been throbbing and when I move my eyes it feels like someone is punching me in the side of the head. I am nauseous and can't focus. What is going on?
