Irregular Periods & Pregnancy Symptoms: What Could It Be?

It is possible that you may be pregnant, as some of the symptoms you mentioned - such as irregular periods, headaches, fatigue, and frequent urination - can be early signs of pregnancy. However, negative pregnancy tests could mean that you are not pregnant, or that it is still too early for the tests to detect the pregnancy hormone (hCG). It is recommended that you wait a few days and take another pregnancy test, or visit a doctor for a blood test to confirm whether or not you are pregnant. The blood test can detect pregnancy earlier than urine tests.

Some other possible causes for your symptoms could be premenstrual syndrome (PMS), stress, infection, certain medications, or other underlying medical conditions. It is always best to seek professional medical advice to determine the cause of your symptoms for accurate diagnosis and appropriate treatment.
