anyone else?

okay so since I have had my daughter my period is heavier and longer than I've ever had it before today is day 9 of my period and it is by far the worse day. I am using super tampons and am changing it every two hours. On top of that, I'm getting very light headed and dizzy to the point I can't even get up. My cramps have always been terrible but dear lord I'd rather go through child birth again and then with these cramps. Does anyont else have these problems?
