Unclear: Cramps can be caused by all sorts of things from constipation, gas, intestinal issues, bladder infections, ovarian cysts and other infections. With a vague symptom such as this there is not a clear cut answer. If you think you might be pregnant check then check a home pregnancy test. They are cheap, reliable and available at any pharmacy.
