Severe abdominal pain on the first day of your period is usually caused by strong uterine contractions triggered by prostaglandins, which are natural chemicals that help the uterus shed its lining. This condition is common in many women. The pain is often felt in the lower abdomen and can sometimes radiate to the lower back or thighs, and may be accompanied by nausea, headache, or fatigue.

Menstrual problems can be treated with over-the-counter pain relief medicines like paracetamol or ibuprofen, which help reduce cramps, and hormonal treatments such as contraceptive pills, which may regulate cycles or reduce heavy bleeding. Regular exercise, a healthy diet, adequate sleep, and stress management may also improve symptoms. Keeping a record of your periods allows your doctor to identify patterns and recommend the most appropriate treatment.

For severe abdominal pain similar to menstrual cramps, you may rest, apply a warm compress to your abdomen, and take over-the-counter pain relievers such as ibuprofen or paracetamol. If the pain is very severe, sudden, or accompanied by fever, vomiting, or unusual bleeding, please see a doctor promptly to rule out any underlying causes and receive appropriate treatment.
