Stress making period way worse

I moved across the country this week and I start school next week. Clearly, I'm VERY stressed. I just started my period today and my cramps are infinitely worse than they have ever been. I was throwing up and having terrible diarrhea today from the cramps. I actually considered going to the hospital because they were so bad. I've taken Advil and it's helped some, but they're still here.
Could the stress be making my cramps worse? How can I reduce my stress to make my period normal again??
