To know if you are pregnant, common early signs to watch for include a missed period, nausea (morning sickness), breast tenderness or changes such as soreness and darkening of the areolas, fatigue, and frequent urination. Some people also experience dizziness, food cravings, and mild cramping. However, these symptoms can overlap with other conditions, so the most reliable way to confirm pregnancy is to take a home pregnancy test after a missed period. If the test is positive, visiting a doctor for confirmation and guidance is recommended. If the test is negative but symptoms persist, a doctor can conduct a blood test for further confirmation.
