The amount of blood you lose varies from girl to girl

The amount of blood you lose during a period varies from girl to girl; your flow may start out light, then get heavier, and then get lighter. Depending on the heaviness of your flow, you’ll lose between 2 to 6 tablespoons of blood each period although for some girls it can be as much as a cup. If you are concerned about the amount you are bleeding, the best thing to do is see you doctor for a quick check up.
