cramps so bad that i puke?

so i have had my period for a year and a half now, and im 15. my cramps get bad but i always pop some mydol and forget about it. but not this time!! i was at school, and i got severe cramps to where i was doubled over & crying in film class. i had to go to the nurse so i layed dowm with a heating pad. that only made it worse!!! so then, as im laying down i start drooling super bad! i feel like im gunna throw up and i puke 3 times because the pain was so bad!! is this normal for a 15 year old to go through?!
