What Causes Lower Abdominal Pain Before Menstruation?

If menstruation is overdue and is accompanied by lower abdominal pain, prompt medical evaluation is essential. Pregnancy-related conditions must be carefully considered—especially ectopic pregnancy, which must be ruled out. If menstruation is delayed by more than seven days beyond the expected date (based on the previous cycle), pregnancy should be strongly suspected. When menstruation is significantly delayed and abdominal pain is present, pregnancy-related disorders warrant heightened clinical attention. Among postmenopausal women, the most common pregnancy-related causes of abdominal pain include ectopic pregnancy and threatened miscarriage. Ectopic pregnancy is a life-threatening gynecological emergency; severe cases can lead to hemorrhagic shock and endanger the woman’s life. Therefore, any woman experiencing delayed menstruation and abdominal pain must undergo pregnancy testing, as these tests help confirm or exclude pregnancy-related conditions.

During menstruation, drinking warm brown sugar water may help alleviate discomfort. It is also important to keep the lower abdomen warm and avoid consuming cold, raw, or excessively spicy foods. If menstrual pain is severe, consult a physician for appropriate oral analgesics to relieve symptoms.

Women should also avoid contact with cold water during their periods. We hope this information proves helpful!
