Hi, Yes, it is possible that you could be pregnant. Lower abdominal pain increased hunger, and frequent urination can be early signs of pregnancy. However, there are also other possible causes of late periods and lower abdominal pain, including hormonal imbalances, stress, ovarian cysts, or pelvic inflammatory disease (PID). If you think you may be pregnant, you can take a home pregnancy test to confirm. These tests are accurate when used correctly, and can detect pregnancy as early as a few days after a missed period. If the test is positive, it is important to schedule an appointment with a healthcare provider for prenatal care. If the test is negative and your period does not start within a week or two, or if you experience other symptoms such as fever or vaginal discharge, it is important to see a healthcare provider for further evaluation. They can perform a physical exam and may recommend additional testing or treatment options based on their assessment. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Priyanka, General & Family Physician
