Hi I'm 17 years old I started my period 2 days ago and this is the worst one of them all I woke up this morning with so much pain were I couldn't move but when I went to the bathroom three far large blood clots fall out after that I got dizzy couldn't move now I'm in the worst pain I'm dizzy even though I'm laying down and I'm nauseous.

Can anyone tell me what I should do or what is wrong with me?
