A missed period with symptoms like nausea or breast tenderness can suggest pregnancy, but it needs confirmation. Use a home pregnancy test with your first morning urine for better accuracy, and follow the instructions carefully to get a reliable result. If the result is unclear, repeat the test after a few days. You can also get a blood test, which provides more accurate confirmation, and once it's positive, plan an early check-up to ensure everything is fine. Avoid delaying the test if your periods are late. If you have pain, unusual bleeding, or confusion about results, seek medical attention. Consult a doctor to confirm the pregnancy and guide the next steps.

Yes, pregnancy is possible as the withdrawal method is not entirely reliable. However, high stress and intense exercise are also very common reasons for delayed periods. Your first step should be to take a home pregnancy test, which will be highly accurate by now. Please do not take any medications to induce your period without consulting a doctor, especially before confirming you are not pregnant. Try to stay calm; this is a very common situation. Take a test first, and then schedule a visit with a healthcare provider to discuss the best next steps for your body.
