Please help.

I'm 14 and recently my period just started today. I've been getting my cycle since I started the 7th grade and even then my cramps were mild. All of a sudden, I've been having cramps that brought me to absolute tears. I couldn't walk, it hurt to stand, and when I do literally anything I feel like crying. It hurts so bad. The pain spreads to my stomach as well. I've been drinking water, gingerale, I'm about to try the tea in a second but I desperately need some input. I'm scared that if I go to the doctor, they'll say I have something very bad going on inside of me. These cramps made me unable to finish school for the day.
