Do periods get worse as you get older?

I am 24. I had my first period when I was 12. Most of my life, I have had really easy periods. No pms and barely any cramping. I hardly even noticed when I had a period. Now, over the last several months, my periods have been getting progressively worse. I have pretty bad pms, the bleeding is heavier and the pain is horrible. I can't stand up straight through the cramping and backache. Also, I feel exhuasted and have a constant headache for at least the first and second days of my cycle. Is this normal? What can I do about it besides going on birth control?
