A delayed period and abdominal pain may be a precursor to the onset of menstruation. The pain is usually not very intense and may be relieved soon with observation or the onset of menstruation. If the symptoms are not relieved, you need to confirm whether you are pregnant. Pregnant women may also show delayed menstruation with symptoms of early pregnancy such as abdominal pain, weakness and loss of appetite. After all these causes have been ruled out, a gynecological examination is needed to determine if there is cervical adhesion or cervical erosion, which causes obstruction of menstrual drainage and triggers abdominal pain. Therefore, such patients need to be seen promptly and receive symptomatic treatment.
