Painful period cramps that are worse than normal may indicate a problem in a reproductive organ. This includes conditions such as endometriosis (when tissue from the uterus is displaced to somewhere else like the pelvic wall or ovaries), uterine fibroids (thick bands of muscular and fibrous tissue in the uterus), ovarian cysts, ovarian cancer (rare), or pelvic inflammatory disease (PID) which is an infection of the reproductive organs, usually from a sexually transmitted disease.The key is to know when you must seek medical care right away. In many cases you can simply wait to see whether it goes away in a few days or call your doctor at a later time if the symptoms persist. I would recommend however that if it doesn't go away within a couple of days you have to go see a doctor or a nurse at a clinic for further evaluation.I experienced the same painful menstrual like cramps before, during and after my period and 3 weeks ago through a laparoscopy found out that I have endometriosis.Good luck
