I had a miscarriage a week ago. i lost a lot of blood. i am bloo supplements but suffering from a terrible headache since.

Anemia: You are probably very low in iron because of your blood loss. You have what is called iron deficiency and blood loss anemia. Headaches are common with this. Make sure you stay well hydrated with water and juice. You will need to be on iron supplements for at least 3-4 months. A blood transfusion would help immediately, but there would be risks. Better to let the iron build you back up.
