Hi and welcome.
This is definitely to be concerned about. Severe abdominal cramping can be due to under lying pathology. There are few conditions which need to be evaluated including hormonal imbalance, pelvic inflammatory disease and fibroids or ovarian cyst. I would suggest you to visit your gynecologist for thorough physical examination and get a base line investigations along with ultrasound scan as well.
Let me know if you have further questions.
