Today i got my peroid and the cramps were so bad i had to call in sick at work

So basically im 16 and have gad my peroid since i was 12 and when i first got it the cramps were nearly unbearable but it never caused me to start throwing up. Any who since then the cramps have gotten better and are now pretty tolerable. Today i got my peroid and the cramps were so bad i had to call in sick at work. I became so tired to the point where everything even thinking seemed like to much. My skin got super sensitive and i started throwing up. I have not experienced any of these things before while on my period before. Normally its light cramps and bloating. I cant take medication cuz it comes right back up, ive tried applying heat to my lower abdomen and exersise as well but nothing is working. I have no clue if this is normal or not and am pretty freaked out. Please help
