"They lose too much blood, replace about half of it, and then lose too much again the following month," he says. "It's like filling up a car with a small hold in the tank." Your period should only fill two to three tablespoons each month. Try the tampon test: If you have to change your tampon more frequently than every two hours, talk to your gyno.
