Probably not. Anything that makes your uterus sore can cause cramping, with or without a menstrual cycle. Infections are common. So is endometriosis. If the problem continues, go see your family doctor.
Am experience pulsating in left low abdomen not pain, accompanied w. missed period, (11D), but neg HPTS<bloating and slight cramping, is this related?
LLQ discomfort. Causes of recurrent llq abdominal discomfort may be identified by first addressing accompanying signs/symptoms so as to localize the organ involved: vaginal discharge or bleeding, alteration in periods, pregnancy risk? Fever, nausea, vomiting, altered stool pattern, blood with stool, tenderness, distension? Painful urination, blood in urine? Recent trauma, herniations? Age? Gender? Risk factors?
