crazy bad period

So this period has been straight from the bowels of hell. Day one I woke up to a blood covered bed and had to jump in the shower. Day two was the same. It's never been that bad right off the bat and today is still just as bad. Should I be concerned? I think I may be anemic because of the amount of blood that was lost I couldn't keep my eyes open. I was so tired I could have slept for weeks. I was so tired I couldn't even spend time with my boyfriend. I read it happens to women who are anemic during their periods and that that is normally the only cause because hormones don't do that. Anyway, I'm concerned about the amount of blood. Halp!
