Women with abdominal cramps can be seen in the following cases: First, pelvic inflammatory diseases leading to abdominal cramps are the most common in the clinic, accompanied by increased vaginal discharge, lumbar acidity, and even low fever. Internal gynecological examination may show pressure pain in the uterus or bilateral adnexal areas, elevated white blood cells or C-reactive protein, and ultrasound may show pelvic fluid or abscess. Secondly, there may be a slight cramping in the abdomen before menstruation, which is related to uterine and pelvic congestion before menstruation.
