Hi my name is deontranese. I am 17 years old and I've been experiencing some cramping in the lower left side of my abdomen. I stopped my period a week ago. What is causing my cramping and I haven't had sex

There is absolutely no way to tell you what's causing the cramping, there are many possibilities. If this is a concern you'll need to see your doctor, no one can give you a valid diagnosis online.

Good luck.
