Possibly pregnant: Take a home pregnancy test. They are reliable, accurate and valid. If it's negative, repeat it in one week. If it's still negative, see your doctor.

Anemia?: Metallic taste in mouth and chronic fatigue are common conditions of anemia, or low iron in your blood. Are you vegetarian/vegan? I would get a blood test from your physician to make sure you do not iron supplements.
