[43F] Experiencing nausea, lightheadedness, and frequent headaches

What might be happening

Based on the symptoms you've described, several conditions could be causing your symptoms:

• Early Pregnancy: Despite the negative test, it's possible you could be experiencing early signs of pregnancy. Home pregnancy tests aren't always accurate, especially if taken too early. The symptoms you're experiencing -- nausea, fatigue, light-headedness, increased urination, and light spotting -- are common in early pregnancy.

  • Confirmation would require a blood test or ultrasound by a healthcare professional.

• Pre-Menstrual Syndrome (PMS) or Hormonal Changes: The symptoms you're experiencing can also be associated with hormonal changes in your body, such as those that occur before your menstrual period.

  • Treatment typically involves lifestyle changes and sometimes medication to manage symptoms.

• Viral Infection: A viral infection could explain your symptoms of fatigue, light-headedness, and slight fever.

  • Rest, hydration, and over-the-counter medication to manage symptoms are typically recommended.

• Dehydration: Dehydration can cause light-headedness, especially upon standing, and increased thirst.

  • Treatment involves rehydrating with water or electrolyte-rich fluids.

Please note that this is not an exhaustive list and other conditions could also be causing your symptoms.

What you can do

1. Retake a home pregnancy test: If your period does not start as expected, consider retaking a home pregnancy test. These tests are most accurate one week after a missed period.

2. Stay Hydrated: Make sure you're drinking enough fluids, especially if you're feeling light-headed or thirsty.

3. Rest: If you're feeling fatigued or unwell, make sure you're getting enough rest.

4. Consult a healthcare professional: Given the range and persistence of your symptoms, it would be a good idea to consult a healthcare professional. They can provide a more accurate diagnosis and appropriate treatment.

What you should look out for

Seek immediate medical attention if you experience:

• Severe abdominal pain
• Heavy vaginal bleeding
• Persistent or worsening headache
• Fainting or loss of consciousness
• Severe dizziness or lightheadedness
