Physically Incapacitated Due to Heavy Period

Hey friends!
So over this past year my periods have been getting heavier and further apart. I did some research, apparently you're only supposed to lose like 2-3T of blood in the entire period? But if the rest of today continues consistently, based on the capacity of the tampons I've been using, I will hit something like 6T just today. Anybody else experience this? What do I do?
