Dealing with extreme period pain

Hello! So I've been dealing with extremely bad period pains the entire time I've had my period. I'm talking throwing up, diarrhea, getting light headed, I can't sleep cause the pain, and just feeling like total crap. I've had to miss school and when I do go to school I'd have to spend over an hour in the nurses office for the pain for the first 2 days of it. I take 2 Midol about every 5 to 6 hours and it does nothing. Please I'm looking for any help! Please!!!
