It is important to note that home pregnancy tests are generally accurate, but there can be instances where they produce false negative results. If you are experiencing pregnancy symptoms such as a growing belly and still getting your period, it is recommended to consult with a healthcare professional for further evaluation. They can conduct a blood test or ultrasound to determine if you are indeed pregnant. There are also other factors that could contribute to the symptoms you are experiencing, such as hormonal imbalances or digestive issues. A medical examination will provide clarity and help identify the cause of your symptoms.
