this can be sign of hypoglecemia. Your body doesn't have enough sugar cells to help maintain your bodyand mainly your brain cells. It will also explain why you feel dizzy. If I were you, I would take a blood test in the morning before eating anything.
I agree that you should see a physician, or at least a dentist. The taste of iron could suggest that you are bleeding from somewhere in your mouth. If it's way in the back, you may not be able to see it. If you are bleeding, that could also explain feeling faint. In any case--bleeding, pregnancy, or something else--have a health practitioner check you out. Good luck.
Still could be....alot of women have a period through out pregnancy. Anyways, you should probably go to the doctor to see why you have these symptoms (if you still do).
I did think that but I've just started my period so i dont think its that. Thanks anyway x
Maybe you should try a pregnancy test....just to rule that out?
