PLEASE HELP

Kloe
Can anyone tell me if I should go to the doctor or hospital Im kinda freaking ou t 
I'm 4 days early 
It's a crime scene blood flow for the past 4 days and by now I'm usually almost done and barely bleeding but it's been constant heavy flow. (Like 2 super tampons and a maxi pad within an hour)
I've had a severe cramps and nothing is helping calming them
Today in the car I had a sudden flow of nausea and I can't stop shaking and my legs feel numb and I just don't know what's happing right now
